Colloquium: Zoo of quantum-topological phases of matter

XG Wen - Reviews of Modern Physics, 2017 - APS
What are topological phases of matter? First, they are phases of matter at zero temperature.
Second, they have a nonzero energy gap for the excitations above the ground state. Third …

Geometric response and disclination-induced skin effects in non-Hermitian systems

XQ Sun, P Zhu, TL Hughes - Physical review letters, 2021 - APS
We study the geometric response of three-dimensional non-Hermitian crystalline systems
with nontrivial point-gap topology. For systems with fourfold rotation symmetry, we show that …

Chiral central charge from a single bulk wave function

IH Kim, B Shi, K Kato, VV Albert - Physical Review Letters, 2022 - APS
A (2+ 1)-dimensional gapped quantum many-body system can have a topologically

Bimetric theory of fractional quantum hall states

A Gromov, DT Son - Physical Review X, 2017 - APS
We present a bimetric low-energy effective theory of fractional quantum Hall (FQH) states
that describes the topological properties and a gapped collective excitation, known as the …

Odd viscosity in two-dimensional incompressible fluids

S Ganeshan, AG Abanov - Physical review fluids, 2017 - APS
In this work, we present observable consequences of a parity-violating odd-viscosity term in
incompressible 2+ 1D hydrodynamics. For boundary conditions depending on the velocity …

Modular commutator in gapped quantum many-body systems
