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…

Long-Time Limits of Local Operator Entanglement in Interacting Integrable Models

J. Alexander Jacoby, Sarang Gopalakrishnan

We explore the long-time behavior of Local Operator Entanglement entropy (LOE) in finite-size interacting integrable systems. For certain operators in the Rule 54 automaton, we pro…

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…

Hamiltonian Reconstruction: the Correlation Matrix and Incomplete Operator Bases

Lucas Z. Brito, Stephen Carr, J. Alexander Jacoby +1

We explore the robustness of the correlation matrix Hamiltonian reconstruction technique with respect to the choice of operator basis, studying the effects of bases that are underc…
