Manifestation of quantum entanglement between harmonic oscillators in de Sitter
Sumanta Chakraborty, Anupam Mazumdar, Ritapriya Pradhan
Two harmonic oscillators interacting through the exchange of a quantum field leads to non-zero entanglement between the two, which is absent for classical interaction. In this work…
Distinguishing Jordan and Einstein frames in gravity through entanglement
Sumanta Chakraborty, Anupam Mazumdar, Ritapriya Pradhan
In general relativity, the use of conformal transformation is ubiquitous and leads to two different frames of reference, known as the Jordan and the Einstein frames. Typically, the…
Perturbation Theory in a Microcanonical Ensemble
Ritapriya Pradhan, Jayanta K. Bhattacharjee
The microcanonical ensemble is a natural starting point of statistical mechanics. However, when it comes to perturbation theory in statistical mechanics, traditionally only the can…
