Topological superconductivity in twisted double-layer high-Tc cuprates: Theory and experimental signatures
Marcel Franz - University of British Columbia
Structures composed of two monolayer-thin d-wave superconductors with a twist angle close to 45° are predicted to form a robust, fully gapped topological superconducting phase with spontaneously broken time-reversal symmetry and protected chiral edge modes. In this talk I will briefly review the… -
Stacking Induced Spontaneous Polarization in Rhombohedral MoS2
Ziliang Ye - University of British Columbia
"The relatively weak van der Waals bond in 2D materials has ushered in a rich new era of stacking engineering. We recently found in rhombohedrally stacked MoS2, a Berry phase contrast between layers can induce an asymmetric interlayer coupling and an out-of-plane spontaneous electrical polarization… -
Recurrent neural networks for many-body physics
Juan Carrasquilla - ETH Zurich
I will discuss our recent work on the use of autoregressive neural networks for many-body physics. In particular, I will discuss two approaches to represent quantum states using these models and their applications to the reconstruction of quantum states, the simulation of real-time dynamics of open… -
Z2 spin liquids in spin-S Kitaev honeycomb model via parton construction
Han Ma - Stony Brook University
Unlike the half spin Kitaev honeycomb model which can be solved by an exact parton construction, the higher spin analogue of it is not solvable and it is still controversial if it exhibits a quantum spin liquid phase. In this talk, I will present a generalized parton construction where each spin-S… -

Non-Fermi liquids and quantum criticality in multipolar Kondo systems
Yong-Baek Kim - University of Toronto
We discuss emergent non-Fermi liquid behaviors in multipolar Kondo systems, where conduction electrons interact with the non-Kramers local moments carrying higher-rank multipolar moments such as quadrupolar and octupolar moments. We first show that unexpected non-Fermi liquid states arise in the… -
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… -
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… -
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… -
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… -
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…
