Gapless Fermionic Systems as Phase-space Topological Insulators: Non-perturbative Results from Anomalies
Taylor L. Hughes, Yuxuan Wang
We present a theory unifying the topological responses and anomalies of various gapless fermion systems exhibiting Fermi surfaces, including those with Berry phases, and nodal stru…

Many-Body Non-Hermitian Skin Effect for Multipoles
Jacopo Gliozzi, Giuseppe De Tomasi, Taylor L. Hughes
In this work, we investigate the fate of the non-Hermitian skin effect in one-dimensional systems that conserve the dipole moment and higher moments of an associated global $\text{…

Decoherence through Ancilla Anyon Reservoirs
Nayan Myerson-Jain, Taylor L. Hughes, Cenke Xu
We explore the decoherence of the gapless/critical boundary of a topological order, through interactions with the bulk reservoir of "ancilla anyons." We take the critical boundary…
