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…
Phase diagram of the quantum Hall state in bilayer graphene
Udit Khanna, Ke Huang, Ganpathy Murthy +5
Bilayer graphene exhibits a rich phase diagram in the quantum Hall regime, arising from a multitude of internal degrees of freedom, including spin, valley, and orbital indices. The…
