Out-of-time-order correlator, many-body quantum chaos, light-like generators, and singular values
Ke Huang, Xiao Li, David A. Huse +1
We study out-of-time-order correlators (OTOCs) of local operators in spatial-temporal invariant or random quantum circuits using light-like generators (LLG) -- many-body operators…
Statistics of noninteracting many-body fermionic states: The question of a many-body mobility edge
Ke Huang, DinhDuy Vu, Sankar Das Sarma +1
In this work, we study the statistics of a generic noninteracting many-body fermionic system whose single-particle counterpart has a single-particle mobility edge (SPME). We first…
Interaction-enhanced many body localization in a generalized Aubry-Andre model
Ke Huang, DinhDuy Vu, Sankar Das Sarma +1
We study the many-body localization (MBL) transition in a generalized Aubry-Andre model (also known as the GPD model) introduced in Phys. Rev. Lett. 114, 146601 (2015). In contrast…
Engineering subharmonic responses beyond prethermalization via Floquet scar states
Ke Huang, Xiao Li
In this work we propose a new scheme to engineer subharmonic responses via scar states in a generalized PXP model. We first show that the generalized PXP model also possesses a ban…
Incommensurate many-body localization in the presence of long-range hopping and single-particle mobility edge
Ke Huang, DinhDuy Vu, Xiao Li +1
We study many-body localization (MBL) in the quasiperiodic - model, focusing on the role of next-nearest-neighbor (NNN) hopping , which introduces a single-particle…
Fermionic many-body localization for random and quasiperiodic systems in the presence of short- and long-range interactions
DinhDuy Vu, Ke Huang, Xiao Li +1
We study many-body localization (MBL) for interacting one-dimensional lattice fermions in random (Anderson) and quasiperiodic (Aubry-Andre) models, focusing on the role of interact…
