Spread complexity as a probe in generalized and long-range Aubry-Andre-Harper models
Triyas Sapui, Tanoy Kanti Konar, Subinay Dasgupta +1
We investigate the spread complexity of quantum quenches in generalized and long-range Aubry-Andre-Harper (AAH) models, encompassing regimes with and without mobility edges. In par…

Ergotropic Mpemba crossings in finite-dimensional quantum batteries
Triyas Sapui, Tanoy Kanti Konar, Aditi Sen De
The quantum Mpemba effect is a counterintuitive phenomenon in which a state initially farther from equilibrium relaxes more rapidly than one that starts nearer to equilibrium. In t…

Genuine multipartite entanglement as a probe of many-body localization in disordered spin chains with Dzyaloshinskii-Moriya interactions
Triyas Sapui, Keshav Das Agarwal, Tanoy Kanti Konar +2
We demonstrate that the quenched average genuine multipartite entanglement (GME) can approach its maximum value in the ergodic phase of a disordered quantum spin model. In contrast…
