Stable valleys in the glassy landscape of a low-density parity-check (LDPC) code
Grace M. Sommers, David A. Huse
Classical low-density parity-check (cLDPC) codes defined on expander graphs are a fundamental ingredient in the construction of good quantum LDPC codes, a recent milestone in quant…
Crystalline Spectral Form Factors
Dmitrii A. Trunin, David A. Huse
We investigate crystalline-like behavior of the spectral form factor in unitary quantum systems with extremely strong eigenvalue repulsion. Using a low-temperature Coulomb gas as a…
Boundary-driven quantum systems near the Zeno limit: steady states and long-time behavior
Eric A. Carlen, David A. Huse, Joel L. Lebowitz
We study composite open quantum systems with a finite-dimensional state space governed by a Lindblad equation …
Quench spectroscopy of amplitude modes in a one-dimensional critical phase
Hyunsoo Ha, David A. Huse, Rhine Samajdar
We investigate the emergence of an amplitude (Higgs-like) mode in the gapless phase of the D XXZ spin chain. Unlike conventional settings where amplitude modes arise from sp…
Absorbing state transitions with discrete symmetries
Hyunsoo Ha, David A. Huse, Rhine Samajdar
Robust phases of matter, which remain stable under small perturbations, are of fundamental importance in statistical physics and quantum information. Recent advances in interactive…
Eigenstate thermalization in thermal first-order phase transitions
Maksym Serbyn, Alexander Avdoshkin, Oriana K. Diessel +1
The eigenstate thermalization hypothesis (ETH) posits how isolated quantum many-body systems thermalize, assuming that individual eigenstates at the same energy density have identi…
