Holomorphic-topological field theories and representation theory
Holomorphic-topological field theories and representation theory
Holomorphic-topological (HT) field theories form a fascinating class of quantum field theories. These theories combine features of topological quantum field theories (TQFT) and conformal field theories (CFT).Due to the mixed holomorphic-topological nature of such theories, they create interactions between TQFT data (e.g., algbras, monoidal categories, etc) and CFT data (e.g., chiral algebras and chiral categories). This leads to exciting new mathematical structures, and connections to integrable systems, quantum topology and many other areas of mathematics. Recently. much progress has been made on the representation-theoretic aspects of HT theories. Examples include:1. (Shifted) Poisson vertex algebras and their quantizations are constructed from local operators in HT theories.2. Dimensional reduction of 4d HT theories lead to integrable systems and solutions of quantum Yang-Baxter equations.3. 4d N=2 theories are linked to representation theory of K-theoretic Coulomb branches, cluster algebra categorifications, wall crossings and elliptic stable envelops.4. New examples of chiral algebras and their dualities are derived from boundary conditions and dualities of 3d HT theories.Moreover, many interesting TQFTs are given by deformations of holomorphic-topological theories. Examples include topological twists of 3d N=4 and 4d N=2 theories. These theories have attracted considerable attention in recent years for their connections to 3d mirror symmetry and the Langlands program. Some of these TQFTs only admit Lagrangian descriptions as HT QFTs, and therefore studying HT theories offers a possible approach for understanding these non-Lagrangian TQFTs.This conference will focus on the representation-theoretic aspects of HT theories, particularly:1. Chiral algebras arising from observables of HT QFT.2. Quantum algebras, including Yangians and quantum affine algebras, and their relation to HT theories.3. Chiral categories and OPE of line operators in HT theories.4. Deformation of HT theories and their relation to chiral algebra deformations.5. Relation between various HT theories under dimensional-reduction.We aim to bring together leading mathematicians and physicists, to inform each other about the recent progress made in this area.:: :: ::

100 Years of Quantum: Perspectives on its Past, Present, and Future
In July 1925, Heisenberg published his paper on matrix mechanics, followed shortly thereafter (in early 1926) by Schrodinger’s paper on wave mechanics. As such, 2025 is the centenary of the modern quantum theory. This conference aims to bring together experts in the history and philosophy of quantum theory and researchers working on various foundational issues to shed new light on the past, present and future of the theory.
The meeting aims to benefit from the useful synergy that exists between historical studies and efforts to push forward the frontier of our knowledge. On one side, the details of the path to discovery of various quantum concepts or applications of quantum ideas can inform contemporary research. For instance, whenever there is a paradigm of thinking that is sufficiently pervasive today that it is difficult to even recognize the possibility of alternatives, familiarity with the debates at the historical origin of this paradigm can help to make explicit what is usually left implicit. On the other side, modern developments can often shed new light on various historical and philosophical issues.
The fact that there is still no broad consensus on many of the conceptual issues that have been controversial since the birth of modern quantum theory suggests that a proper understanding of these remains to be achieved. The occasion of the quantum centenary provides a good opportunity for the community to develop a broader perspective on these issues, draw connections between research programs that aim to address them, and set objectives for future research.
The aim is to have two types of talks concerning the history: those that present novel takes on well-studied historical topics and those that address more unconventional historical questions. The second category aims to include talks on the history of a variety of subfields of quantum theory, such quantum information, quantum field theory, quantum optics, quantum logic, quantum chemistry, quantum gravity, quantum matter and quantum foundations..
Conference topics include:
- The prehistory of modern quantum theory
- The historical development of modern quantum theory
- The discovery of Important concepts in quantum theory (the uncertainty principle, wave-particle duality, particle statistics, the no-cloning theorem, teleportation, etc.)
- The discovery of important no-go results (von Neumann’s no-go theorem, the 1935 Einstein-Podolsky-Rosen argument, Bell’s theorem, the Kochen-Specker theorem)
- The history of quantum information, quantum field theory, quantum optics, quantum logic, quantum chemistry, quantum gravity, and quantum matter
- The sociology of quantum physics
The conference will include invited as well as contributed talks.:: :: ::

Charting the Future Symposium
Charting the Future Symposium: Big questions in particle physics, strong gravity, and cosmology over the next 25 years
Join us for a special symposium celebrating Perimeter’s 25th anniversary. This event offers a unique opportunity to unite Perimeter alumni and friends in the fields of cosmology, particle physics, and strong gravity with our extended community, reflect on a quarter-century of discovery, and look ahead to the challenges and opportunities that will shape the next 25 years of fundamental physics.
Over the past quarter-century, we have witnessed transformative advances across our fields. In particle physics, the discovery of the Higgs boson crowned decades of effort, while precision experiments continue to probe the Standard Model and search for new physics. In strong gravity, the direct detection of gravitational waves has opened a new observational window onto black holes, neutron stars, and the very fabric of spacetime. In cosmology, precision measurements of the cosmic microwave background and large-scale structure have revolutionized our understanding of the universe’s origins and evolution, even as dark matter and dark energy remain profound mysteries.
As we look to the future, a new generation of experiments, observations, and theoretical ideas promises to drive further revolutions. From uncovering physics beyond the Standard Model to probing the nature of spacetime and the earliest moments of the cosmos, the next 25 years are poised to be as transformative as the last.
This symposium will bring together leading researchers, young scientists, alumni, and friends to celebrate past achievements, and imagine the discoveries yet to come. We invite you to be part of this landmark event at Perimeter Institute, as we honor the spirit of curiosity, ambition, and collaboration that has defined our journey so far — and will carry us forward.

Cosmic Ecosystems
In the past three decades, one of the most transformative insights in cosmology has been the realisation that the formation and evolution processes of cosmic structures such as supermassive black-holes, galaxies and clusters are deeply interconnected with the vast cosmic web that underpins the Universe. These processes do not happen in isolation, but are part of a dynamic ecosystem where matter and energy flow across scales, driving the growth and transformation of cosmic environments. Understanding this complex system, in particular the circum-galactic medium (CGM), is not only key to deciphering how matter is cycled and redistributed through accretion via filaments and outflows from AGN and supernovae, but also crucial for unlocking the next generation of discoveries in areas such as dark matter, the behaviour of the cosmic web, the forces that shape cosmic evolution, and more.This conference seeks to bring together cosmologists and astrophysicists to foster collaborative exploration of these interconnected cosmic ecosystems. By focusing on how structures interact with their environments across cosmic scales, this conference aims to catalyse groundbreaking discoveries in both astronomy and physics, providing fresh insights into the forces that govern the Universe. Special attention will be given to the joint analysis of large-scale structure and weak gravitational lensing data from surveys such as DESI, Euclid, LSST and Roman with CMB data from the Simons Observatory and CMB-S4, as well as how these can be integrated with observations of JWST, and existing and upcoming observations of X-ray emission, UV/X-ray absorption toward quasars, 21-cm emission, and FRBs.The goal is to explore the complementarity of these data sets and how their alignment can provide new insights into the interconnected processes shaping cosmic environments, particularly through joint modelling and simulations of many phases of gas and feedback across different regimes. Attention will also be given to bridging the gap between how cosmologists and astronomers approach the CGM, either top-down large-scale and hot and virial phase, vs bottom-up, cooler phases, at smaller scales.Topics will include:· Cosmic mass budget, including a census of where the baryons are.· Effect of baryons on dark matter structures on small and large scales.· Cosmic evolution of large-scale structures.· Bridging the gap between different probes.
Please see the Conference Themes for a more complete list of example topics.The time has never been more right to unify these fields, as advances in observation, theory and simulations are poised to open new paths to revealing the cosmos’ most profound mysteries.:: :: ::

Lee's Fest: Quantum Gravity and the Nature of Time
What is time? Is it fundamental or emergent? This question lies at the foundation of contemporary physics and provides a key to unlocking some of its most challenging open problems, from quantum gravity to cosmology. The quest to understand time extends beyond the realm of physics, providing a privileged standpoint to address questions in diverse fields such as philosophy, mathematics, and computer science.
In this conference, we explore the nature of time from many different perspectives. This is the occasion to honor Perimeter’s “Master of Time,” Lee Smolin, and to celebrate his seminal scientific contributions. Lee Smolin is a founding faculty member of Perimeter Institute and a primary inspiration behind its spirit and design. This is an opportunity to journey back in time to the origins of some of the groundbreaking initiatives that Lee helped develop, and to look forward to future developments inspired by his achievements. The conference focuses on time but also on the foundations of quantum mechanics and the quest for quantum gravity, particularly Loop Quantum Gravity, of which Lee Smolin is a co-creator. In the spirit of Lee Smolin, the conference celebrates the interdisciplinary nature of the journey toward quantum gravity, with contributions from physics, mathematics, computer science, and philosophy.

Computing Quantum Gravity Workshop
A key task for many quantum gravity approaches is the development of effective numerical tools, in order to be able to extract physical predictions. This does apply in particular to approaches focusing on the Lorentzian path integral / Lorentzian spacetimes. The main aim of the workshop is to learn and develop methods to deal with Lorentzian signature. This will be a hands-on workshop, where projects will be pursued in small groups.

Theory + AI Workshop: Theoretical Physics for AI
This 5-day program will explore the intersection of AI and fundamental theoretical physics. The event will feature two components, a symposium and a workshop, centered around two complementary themes: AI for theoretical physics and theoretical physics for AI.
The program will begin on April 7 and 8 with a large symposium with speakers and panel discussions focusing on the promise of AI to accelerate progress in theoretical physics. These talks will address the possibilities and challenges associated with AI ‘doing science.’ The event will bring together physicists, engineers, AI researchers, and entrepreneurs to collect different perspectives on what the future of theoretical physics will look like, the engineering challenges we should expect along the way, what tools and collaborations will be needed to help get us there, and what exciting steps are already underway.
Registration for the symposium is available on the symposium website.
The symposium will be followed by a workshop on April 9, 10, 11 focusing on developing a theoretical framework for AI enabling the development of reliable, robust, and interpretable AI models for physics. Recent advances in theoretical foundations of AI, inspired by techniques from string theory, quantum field theory (QFT), and statistical physics, have uncovered parallels between AI systems and physical theories, utilizing methods like renormalization group (RG) flows, Feynman path integrals etc. to deepen understanding of deep neural networks (DNNs), generative AI (e.g., LLMs and diffusion models), and scaling laws. Key topics include physics-informed optimization and learning, the role of RG and QFT for DNNs and generative AI, and the application of physics to AI interpretability. Through interdisciplinary dialogue, the event aims to foster collaborations, advance the theoretical foundations of AI, and explore its potential in areas like theoretical physics and mathematics.Speakers:

Magnetic Fields Around Compact Objects Workshop
In the vicinity of neutron stars and black holes, where spacetime is strongly curved, magnetic fields can power many of the violent phenomena that we observe across the entire electromagnetic spectrum, from accretion and jet launching, to magnetar flares and pulsar emission. In the last decades, our theoretical understanding of the role of magnetic fields in these extreme environments has greatly improved through numerical simulations of magnetohydrodynamical fluids and charged kinetic particles; however, many open and important questions remain. Our observational capabilities and computational resources will keep growing dramatically in the next few years, allowing us to explore high-energy astrophysics in unprecedented regimes. Improving our knowledge of how magnetic fields, matter, and gravity interact with each other is a crucial piece in the new era of multimessenger astrophysics.This workshop will gather experts from a wide range of disciplines within physics and astrophysics to present state-of-the-art advances in theoretical models of magnetic fields and high-energy plasma in different contexts, from neutron star mergers to supermassive black holes, and from micro scales to macro scales.Scientific Organizers:
