Concentration of OTOC and Lieb-Robinson velocity in random Hamiltonians
Chi-Fang Chen
The commutator between operators at different space and time has been a diagnostic for locality of unitary evolution. Most existing results are either for specific tractable (rando…
Finite speed of quantum scrambling with long range interactions
Chi-Fang Chen, Andrew Lucas
In a locally interacting many-body system, two isolated qubits, separated by a large distance , become correlated and entangled with each other at a time . This finit…
Entanglement Wedge Reconstruction using the Petz Map
Chi-Fang Chen, Geoffrey Penington, Grant Salton
At the heart of recent progress in AdS/CFT is the question of subregion duality, or entanglement wedge reconstruction: which part(s) of the boundary CFT are dual to a given subregi…
Origin of the Drude peak and of zero sound in probe brane holography
Chi-Fang Chen, Andrew Lucas
At zero temperature, the charge current operator appears to be conserved, within linear response, in certain holographic probe brane models of strange metals. At small but finite t…
