Quantum Spacetime in the Cosmos: From Conception to Reality
On Demand Recording: https://pirsa.org/C23035
The nature of space and time is one of the most foundational mysteries in both Physics and Philosophy. At the heart of this mystery are the two most successful theories of nature: Einstein's theory of relativity, an elegant and precise description of the geometry of our universe on large scales, and Quantum Mechanics, outlining accurate laws of interaction in the subatomic world. But these two great triumphs of 20th century physics remain inherently inconsistent, contradictory in their most basic principles, such as locality and causality. Nonetheless, the experimental domains or natural phenomena where these contradictions become manifest have remained elusive, and it is not clear that a century of theoretical investigation into quantum gravity is anywhere close to being verified in nature.
Arguably, this disconnect is our greatest and most foundational challenge in the history of Physics; despite groundbreaking progress in both theory and observations of quantum spacetimes, these two endeavours are moving farther apart. Successfully responding to this century-old challenge could require rethinking the epistemology of fundamental physics. While physicists are trained to push the frontiers of knowledge, developing a grand vision of the arch of history, and where we are (or should be) heading is a more interdisciplinary endeavor, requiring insights from theory and observations, but also philosophy and history.
We plan a focused, interactive, and highly interdisciplinary workshop, involving the world’s best theorists, observers, experimentalists, and philosophers, within a supportive, inclusive, and diverse environment, in order to kick start a long term initiative that might be our best bet to make significant progress towards uncovering the quantum nature of spacetime.Sponsorship provided by:

Largest Cosmological Surveys and Big Data Science
The tremendous success of Cosmic Microwave Background (CMB) observations, by WMAP and Planck, have heralded an era in precision cosmology. The large scale structures (LSS) in our Universe, particularly at low redshifts, have also been mapped out in great detail over the last decade by surveys such as SDSS. Ongoing surveys such as the DES, KiDS and HSC are pushing this frontier to higher redshifts. The near future will see further advances with DESI, PFS, Euclid and LSST continuing the legacy of wide area surveys. We will also get data in X-ray from eROSITA, and 21 cm surveys such as CHIME and BINGO followed by SKA in the not so far future. Hand-in-hand, the next generation CMB S4, CMB-HD observations are on the cards; especially CMB polarization and spectral distortion experiments would provide an unprecedented view of the early Universe allowing us to look far beyond the last scattering surface.The proposed program aims to : Expose young researchers to the forefront of Cosmology rese...

Mini-Course of Numerical Conformal Bootstrap
This school will be an advanced course on the numerical bootstrap. In the lectures, we will discuss advanced theoretical aspects of numerical bootstrap and algorithms. In the tutorials, we will demonstrate how to use simpleboot/hyperion and help the participants to run bootstrap computation on their own clusters. Main examples are 3D Ising, O(2), O(3), Gross-Neveu-Yukawa CFTs.
The school will consist of one lecture in the morning and two tutorials in the afternoon (one tutorial for simpleboot (by Ning Su) and another one for hyperion (by Aike Liu).
Course materials, including tutorials, slides, and sample codes, can be found at https://gitlab.com/AikeLiu/Bootstrap-Mini-Course
This event is supported by the Simons Collaboration on The Nonperturbative Bootstrap (https://bootstrapcollaboration.com/).

Inaugural meeting of Asian-Oceanian Women in Mathematics (HYBRID)
Asian-Oceanian Women in Mathematics (AOWM) was formed on August 1, 2022, in online mode, with the support of the CWM members of the IMU, in order to facilitate interactions among women mathematicians in these regions. AOWM hopes to provide an empathetic platform to women mathematicians to share their concerns, and to highlight and bring to the forefront their achievements.In this connection, we will have the first (hybrid) meeting of the AOWM under the auspices of ICTS, Bangalore. One of the primary goals of this meeting is to decide the future course of academic activities in these regions. We also plan to have a number of lectures by distinguished as well as young promising women mathematicians. Further, we will have interactive sessions in hybrid mode with women students and postdocs from all over the world to enlighten them on various career opportunities in research, and the means and support systems available to overcome any challenges they might meet in their pursuits.

Causal Inference & Quantum Foundations Workshop
Recently we have seen exciting results at the intersection of quantum foundations and the statistical analysis of causal hypotheses by virtue of the centrality of latent variable models to both fields.
In this workshop we will explore how academics from both sides can move the shared frontiers forward. Towards that end, we are including extensive breakout collaboration opportunities in addition to formal presentations. In order to make concrete progress on problems pertinent to both communities, we have selected the topic of causal models with restricted cardinality of the latent variables as a special focus for this workshop.

Lunar Gravitational-Wave Detection
Lunar exploration has become a strategic objective of space agencies worldwide. These programs offer extraordinary opportunities for science as well. Gravitational-wave (GW) detection on the Moon already emerged as a revolutionary idea during the Apollo era. Today, technologies exist to realise a GW detector on the Moon. Lunar detectors would have the capability to open the decihertz band to GW observations with enormous opportunities for breakthrough GW and multi-messenger observations. The goal of this meeting is to discuss mission concepts for lunar GW detection, payload technologies, GW science, as well as lunar geophysics, which plays a crucial role in the planning of these missions. This meeting also will include scientists who are working on other mission concepts for decihertz GW detection to facilitate a meaningful exchange of ideas and techniques. Another aim of this meeting is to help to step up the Indian presence in the international efforts to prepare a science white pape...

Quantum Matter (2022/2023)
Matter is quantum. Growing experimental results on materials, natural and synthetic (ion traps, cold atoms etc.,) and concomitant theoretical developments make `quantum matter' an exciting field. There is also a growing interplay of quantum matter physics and quantum information/computation. With a focus on concepts I plan to discuss key phenomenology, quantum models and theory. -
Quantum Gravity (2022/2023)
The main focus of this course is the exploration of the symmetry structure of General Relativity which is an essential step before any attempt at a (direct) quantization of GR. We will start by developing powerful tools for the analysis of local symmetries in physical theories (the covariant phase space method) and then apply it to increasingly complex theories: the parametrized particle, Yang--Mills theory, and finally General Relativity. We will discover in which ways these theories have similar symmetry structures and in which ways GR is special. We will conclude by reviewing classical results on the uniqueness of GR given its symmetry structure and discuss why it is so hard to quantize it. In tutorials and homeworks, through the reading of articles and collegial discussions in the classroom---as well as good old exercises---you will explore questions such as "Should general relativity be quantized at all? Is a single graviton detactable (even in principle)?", "What is the meaning of the wave functions of the universe?", "Can we do physics without time?".
