Harnessing non-Hermiticity for efficient quantum state transfer
Sejal Ahuja, Keshav Das Agarwal, Aditi Sen De
The non-Hermitian Hamiltonian describes the effective dynamics of a system coupled to a continuously measured bath, and can exhibit anti-unitary symmetries that give rise to except…

Enhancing work-extraction in quantum batteries via correlated reservoirs
Sejal Ahuja, Tanoy Kanti Konar, Aditi Sen De
Going beyond isolated system dynamics, we examine how local and spatially correlated reservoirs influence the work extraction in quantum batteries. By employing a one-dimensional s…

Expediting quantum state transfer through the long-range extended XY model
Sejal Ahuja, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Going beyond short-range interactions, we explore the role of long-range interactions in the extended XY model for transferring quantum states through evolution. In particular, emp…
