Simplicity III
This crossdisciplinary workshop gathers theorists who have been working on novel approaches to understanding the structure of the Standard Model and its link to cosmology and gravity. It follows the previous Simplicity I and II workshops at Princeton University (2014) and Fermilab (2016) and will be a small informal meeting with plenty of room for discussions.

Cosmological Frontiers in Fundamental Physics 2019
The workshops focuses on novel frontiers in observational cosmology and astrophysics and how they shed light fundamental questions in understanding the universe. Registration for this workshop is now open.

Boundaries and Defects in Quantum Field Theory
Boundaries and defects play central roles in quantum field theory (QFT) both as means to make contact with nature and as tools to constrain and understand QFT itself. Boundaries in QFT can be used to model impurities and also the finite extent of sample sizes while interfaces allow for different phases of matter to interact in a controllable way. More formally these structures shed light on the structure of QFT by providing new examples of dualities and renormalization group flows. Broadly speaking this meeting will focus on three areas: 1) formal and applied aspects of boundary and defect conformal field theory from anomalies and ctheorems to topological insulators 2) supersymmetry and duality from exact computations of new observables to the construction of new theories and 3) QFT in curved space and gravity from holographic computations of entanglement entropy to ideas in quantum information theory. Registration for this event is now open.

Bootstrap 2019
Quantum field theory (QFT) is a universal language for theoretical physics describing the Standard Model gravity early universe inflation and condensed matter phenomena such as phase transitions superconductors and quantum Hall fluids. A triumph of 20th century physics was to understand weakly coupled QFTs: theories whose interactions can be treated as small perturbations of otherwise freely moving particles. However weakly coupled QFTs represent a tiny island in an ocean of possibilities. They cannot capture many of the most interesting and important physical phenomena from the strong nuclear force to high temperature superconductivity.The critical challenge for the 21st century is to understand and solve strongly coupled QFTs. Meeting this challenge will require new physical insight new mathematics and new computational tools. Our collaboration combines deep knowledge of novel nonperturbative techniques with a concrete plan for attacking the problem of strong coupling. The starting point is the astonishing discovery that in numerous physical systems there is a unique quantum field theory consistent with general principles of symmetry and quantum mechanics. By analyzing the full implications of these general principles one can make sharp predictions for physical observables without resorting to approximations.This strategy is called the Bootstrap the topic of this three week program.

TriInstitute Summer School on Elementary Particles 2018
The 2018 TriInstitute Summer School on Elementary Particles (TRISEP) will be held July 920 2018 in Perimeter Institute for Theoretical Physics Waterloo ON, Canada. TRISEP is an international summer school organized jointly by the Perimeter Institute for Theoretical Physics, SNOLAB, and TRIUMF Canada s laboratory for particle and nuclear physics. TRISEP will feature lectures by leading experts in the field of particle physics in its broadest sense and is designed to be very interactive with ample time for questions, discussions and interaction with the speakers. The school is intended for graduate students of all levels who were already exposed to quantum field theory. For further information, please visit http:///.trisep.ca

Asymptotic Safety in a Dark Universe
The asymptotic safety paradigm is currently emerging as a highly promising idea for BeyondStandardModel physics with key progress in asymptotically safe quantum gravity and asymptotically safe matter models. The last years have seen not only the development of asymptotically safe gravitymatter models but also the discovery of asymptotically safe beyond Standard Model matter models that are under control in perturbation theory. New exciting avenues in (astro) particle physics are now waiting to be explored. For example although the nature of dark matter is a longstanding riddle it is a fact that experimental searches have so far not provided any direct clues but have instead come up with ever more stringent constraints on theoretically preferred regions of parameter space for darkmattermodels. Thus the key to unraveling this riddle could be a new theoretical paradigm to guide model builders. This workshop aims at exploring whether asymptotic safety can be a candidate for this new paradigm. We aim to bring together experts on phenomenological models and quantum gravity to probe both the theoretical viability and empirical signatures of asymptotically safe extensions of the standard model that include gravity. To facilitate a highly productive meeting that can trigger new collaborations each talk will be followed up by 1520 minutes discussion time. Further each day of the workshop will feature a dedicated discussion session. Participants will be encouraged to contribute questions for the discussion both before as well as during the workshop. The last day of the workshop will conclude with a roadmap discussion during which all participants will be given the opportunity to propose concrete suggestions for followup work that might lead into future joint projects.

Searching for New Particles with Black Hole Superradiance
Black hole superradiance is a fascinating process in general relativity and a unique window on ultralight particles beyond the standard model. Bosons  such as axions and dark photons  with Compton wavelengths comparable to size of astrophysical black holes grow exponentially to form large clouds spinning down the black hole in the process and produce monochromatic continuous gravitational wave radiation. In the era of gravitational wave astronomy and increasingly sensitive observations of astrophysical black holes and their properties superradiance of new light particles is a promising avenue to search for new physics in regimes inaccessible to terrestrial experiments. This workshop will bring together theorists data analysts and observers in particle physics gravitational wave astronomy strong gravity and high energy astrophysics to explore the signatures of black hole superradiance and to study the current and future possibilities of searching for new particles with black holes.

Gauge Theory, Geometric Langlands and Vertex Operator Algebras
The workshop will explore the relation between boundary conditions in fourdimensional gauge theory the Geometric Langlands program and Vertex Operator Algebras.
