Intrinsically gapless symmetry-protected topology
Andrew Potter - University of British Columbia , Andrew Potter
While sharply-quantized topological features are conventionally associated with gapped phases of matter, there are a growing number of examples of gapless systems with topologically protected edge states. A particularly striking set of examples are "intrinsically gapless" symmetry-protected…
Emergent anomalies and generalized Luttinger theorems in metals and semimetals
Anton Burkov - University of Waterloo
Luttinger's theorem connects a basic microscopic property of a given metallic crystalline material, the number of electrons per unit cell, to the volume, enclosed by its Fermi surface, which defines its low-energy observable properties. Such statements are valuable since, in general, deducing a low…
Measurement as a shortcut to long-range entangled quantum matter
Tsung-Cheng Lu (Peter) - University of Maryland, College Park
The preparation of long-range entangled states using unitary circuits is limited by Lieb-Robinson bounds, but circuits with projective measurements and feedback (``adaptive circuits'') can evade such restrictions. We introduce three classes of local adaptive circuits that enable low-depth…
QFT2 - Quantum Electrodynamics - Afternoon Lecture
Cliff Burgess - McMaster University
This course uses quantum electrodynamics (QED) as a vehicle for covering several more advanced topics within quantum field theory, and so is aimed at graduate students that already have had an introductory course on quantum field theory. Among the topics hoped to be covered are: gauge invariance for…
A minimalist's approach to the physics of emergence
Liujun Zou - National University of Singapore
One of the central themes of condensed matter physics is the emergence of universality classes. In general, it is highly complex to determine which universality class emerges in a quantum matter based on its microscopic properties. In this talk, I will argue that the perspective of quantum anomaly…
dS in N=2 super Liouville
Beatrix Muehlmann - McGill University
In my talk I will discuss the Euclidean gravitational path integral of N=2 (timelike) Liouville theory on a two-sphere. We view N= 2 Liouville as a gauge fixed form of a 2d supergravity theory coupled to an N=2 superconformal field theory. N=2 super Liouville admits a positive cosmological constant…
New ALP probes from light meson decays
Stefania Gori - University of California, Santa Cruz
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons and pions benefit from their small total decay widths and the availability of very large datasets. In this talk, we first give an overview of new opportunities to…
Synthesis of many-body quantum states using group-IV (Ge/Si) quantum devices
Joe Salfi - University of British Columbia
Quantum dot arrays are an emerging system to synthesize controlled many-body quantum states for quantum simulation and computation. When cooled to a low temperature, each quantum dot acts as a site on which the number of half-integer spin particles can be controlled using voltages applied to gates…
Functional renormalization group formalism for non-Fermi liquids and the antiferromagnetic quantum critical metal
Sung-Sik Lee - McMaster University
We develop a field-theoretic functional renormalization group formalism for field theories of metals that include all gapless modes around the Fermi surface. Due to the presence of intrinsic scales (Fermi momenta), the usual notion of scale invariance and renormalizable field theory need to be…
