Resolving Hall and dissipative viscosity ambiguities via boundary effects
Pranav Rao, Barry Bradlyn
We examine the physical implications of the viscous redundancy of two-dimensional anisotropic fluids, where different components of the viscosity tensor lead to identical effects i…
Lecture Notes on Berry Phases and Topology
Barry Bradlyn, Mikel Iraola
In these notes, we review the role of Berry phases and topology in noninteracting electron systems. Topics including the adiabatic theorem, parallel transport, and Wannier function…
An accurate tight binding model for twisted bilayer graphene describes topological flat bands without geometric relaxation
Shivesh Pathak, Tawfiqur Rakib, Run Hou +4
A major hurdle in understanding the phase diagram of twisted bilayer graphene (TBLG) are the roles of lattice relaxation and electronic structure on isolated band flattening near m…

Quantum Circuits Reproduce Experimental Two-dimensional Many-body Localization Transition Point
Joey Li, Amos Chan, Thorsten B. Wahl
While many studies point towards the existence of many-body localization (MBL) in one dimension, the fate of higher-dimensional strongly disordered systems is a topic of current de…
Nearly-frustration-free ground state preparation
Matthew Thibodeau, Bryan K. Clark
Solving for quantum ground states is important for understanding the properties of quantum many-body systems, and quantum computers are potentially well-suited for solving for quan…
Correlated Hofstadter Spectrum and Flavor Phase Diagram in Magic Angle Graphene
Jiachen Yu, Benjamin A. Foutty, Zhaoyu Han +8
In magic angle twisted bilayer graphene (MATBG), the moiré superlattice potential gives rise to narrow electronic bands1 which support a multitude of many-body quantum phases. Furt…
Crystalline Responses for Rotation-Invariant Higher-Order Topological Insulators
Julian May-Mann, Taylor L. Hughes
Two-dimensional higher-order topological insulators can display a number of exotic phenomena such as half-integer charges localized at corners or disclination defects. In this pape…
Simulating Quantum Mechanics with a -term and an 't Hooft Anomaly on a Synthetic Dimension
Jiayu Shen, Di Luo, Chenxi Huang +4
A topological -term in gauge theories, including quantum chromodynamics in 3+1 dimensions, gives rise to a sign problem that makes classical Monte Carlo simulations impractical.…
