Non-local correlation and entanglement of ultracold bosons in the two-dimensional Bose-Hubbard lattice at finite temperature
Ulli Pohl, Sayak Ray, Johann Kroha
We investigate the temperature-dependent behavior emerging in the vicinity of the superfluid (SF) to Mott-insulator (MI) transition of interacting bosons in a two-dimensional optic…

Fingerprint of chaos and quantum scars in kicked Dicke model: An out-of-time-order correlator study
Sudip Sinha, Sayak Ray, Subhasis Sinha
We investigate the onset of chaos in a periodically kicked Dicke model (KDM), using the out-of-time-order correlator (OTOC) as a diagnostic tool, in both the oscillator and the spi…
