Correlations in few two-component quantum walkers on a tilted lattice
Saubhik Sarkar, Tomasz Sowiński
We study the effect of inter-component interactions on the dynamical properties of quantum walkers. We consider the simplest situation of two indistinguishable non-interacting walk…

Characterization of an operational quantum resource in a critical many-body system
Saubhik Sarkar, Chiranjib Mukhopadhyay, Abolfazl Bayat
Quantum many-body systems have been extensively studied from the perspective of quantum technology, and conversely, critical phenomena in such systems have been characterized by op…

Interspecies entanglement with impurity atoms in a lattice gas
Saubhik Sarkar, Suzanne McEndoo, Dominik Schneble +1
The dynamics of impurity atoms introduced into bosonic gases in an optical lattice have generated a lot of recent interest, both in theory and experiment. We investigate to what ex…
