Twin-paradox and Entanglement
K. Hari, Subhajit Barman, Dawood Kothawala
We study the quantum version of the classical twin paradox in special relativity by replacing the twins with quantum detectors, and studying the transitions and entanglement induce…

Radiative process of tripartite entangled probes in inertial motion
Subhajit Barman, K. Hari
We study the radiative process of three entangled quantum probes initially prepared in a tripartite W state. As a basic set-up, we consider the probes to be inertial in flat spacet…

Entanglement between accelerated probes in a de Sitter spacetime
Mayank, K. Hari, Subhajit Barman +1
We initiate an investigation into features of vacuum entanglement as probed by accelerated quantum probes in curved spacetime. Focussing specifically on de Sitter (dS) spacetime wi…
