CHIMEFRB Collaboration Meeting
Collection Number C18035

Cosmological Frontiers in Fundamental Physics 2019
22 talksCollection Number C19037The 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.

Dynamics and Black Hole Imaging
Collection Number C19051With the advent of black hole imaging, we are now moving forward to black hole cinema. This workshop aims to collect the expertise across the Event Horizon Telescope Collaboration to develop, implement and apply methods to access and interpret variability in M87 and Sgr A*. The goal is to lay the foundation for the first publications based on black hole movies.

Boundaries and Defects in Quantum Field Theory
21 talksCollection Number C19035Boundaries 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
11 talksCollection Number C19026Quantum 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.

Machine Learning for Quantum Design
30 talksCollection Number C19025Machine learning techniques are rapidly being adopted into the field of quantum manybody physics including condensed matter theory experiment and quantum information science. The steady increase in data being produced by highlycontrolled quantum experiments brings the potential of machine learning algorithms to the forefront of scientific advancement. Particularly exciting is the prospect of using machine learning for the discovery and design of quantum materials devices and computers. In order to make progress the field must address a number of fundamental questions related to the challenges of studying manybody quantum mechanics using classical computing algorithms and hardware. The goal of this conference is to bring together experts in computational physics machine learning and quantum information to make headway on a number of related topics including: Datadrive quantum state reconstruction Machine learning strategies for quantum error correction Neuralnetwork based wavefunctions Nearterm prospects for data from quantum devices Machine learning for quantum algorithm discovery Registration for this event is now closed



ManyBody States and Dynamics Workshop II
8 talksCollection Number C19024On Thursday June 13 the Institute for Quantum Computing (IQC) and Perimeter Institute for Theoretical Physics (PI) will participate in the oneday ManyBody States and Dynamics Workshop II. The goal of the workshop is to describe ongoing efforts to experimentally realize quantum manybody states and dynamics and discuss interesting classes of states and dynamics that could be targeted. Experimentalists working on several platforms (such as photons atom and ion traps superconducting qubits excitonpolaritons or NMR) and theoreticians specialized in manybody theory (entanglement topological order gauge theories criticality chaos error correction holography) and numerical simulations (exact diagonalization Monte Carlo DMRG tensor networks) will meet for a morning workshop to identify and discuss common interests.

Quantum Matter: Emergence & Entanglement 3
24 talksCollection Number C19021This third workshop of the Perimeter Institute series Emergence and Entanglement will center around four major frontiers in quantum matter research: (i) topological matter including recently discovered phases in three dimensions and new routes toward experimental realization (ii) critical states of matter especially interacting CFTs in 2+1 dimensions and dualities (iii) stateoftheart numerical approaches to tackle such manybody problems (e.g. DMRG MERA Monte Carlo) and (iv) quantum dynamics and thermalization.

PICITA Day 2019
6 talksCollection Number C19016This is an ongoing series of meetings held two or three times per year between researchers at Perimeter Institute and CITA. The goal of these meetings is to share new ideas and encourage interaction in PI and CITA's common fields of interest through a series of informal talks followed by discussions.
