Strong Eigenstate Thermalization from Mean-Ergodic Non-chaotic Dynamics
Avadhut V. Purohit, Harshit Sharma, Udaysinh T. Bhosale
We report an example of a many-body system, derived from the double kicked top (DKT), with non-chaotic yet mean-ergodic dynamics that displays \textit{strong} eigenstate thermaliza…

Exact Solvability and Integrability Signatures in a Periodically Driven Infinite-Range Spin Chain: The Case of Floquet interval
Harshit Sharma, Sashmita Rout, Avadhut V. Purohit +1
We study the signatures of quantum integrability (QI) in a spin chain model, having infinite-range Ising interaction and subjected to a periodic pulse of an external magnetic field…
