Long-lived local quantum coherences from hydrodynamic large deviations
Ewan McCulloch, J. Alexander Jacoby, Sarang Gopalakrishnan
We develop a framework to describe how quantum coherences between distinct charge sectors evolve under generic charge-conserving dynamics. Our framework captures the nonperturbativ…
Spectral properties and coding transitions of Haar-random quantum codes
Grace M. Sommers, J. Alexander Jacoby, Zack Weinstein +2
A quantum error-correcting code with a nonzero error threshold undergoes a mixed-state phase transition when the error rate reaches that threshold. We explore this phase transition…
Subexponential decay of local correlations from diffusion-limited dephasing
Ewan McCulloch, J. Alexander Jacoby, Curt von Keyserlingk +1
Chaotic quantum systems at finite energy density are expected to act as their own heat baths, rapidly dephasing local quantum superpositions. We argue that in fact this dephasing i…
Spectral gaps of local quantum channels in the weak-dissipation limit
J. Alexander Jacoby, David A. Huse, Sarang Gopalakrishnan
We consider the dynamics of generic chaotic quantum many-body systems with no conservation laws, subject to weak bulk dissipation. It was recently observed [T. Mori, arXiv:2311.103…
