Retarded resonance Casimir-Polder interaction of a uniformly rotating two-atom system
Saptarshi Saha, Chiranjeeb Singha, Arpan Chatterjee
We consider here, a two-atom system is uniformly moving through a circular ring at an ultra-relativistic speed and weakly interacting with common external fields. The vacuum fluctu…
How the mass of a scalar field influences Resonance Casimir-Polder interaction in Schwarzschild spacetime
Arpan Chatterjee, Saptarshi Saha, Chiranjeeb Singha
\emph{Resonance Casimir-Polder interaction(RCPI)} occurs in nature when one or more atoms are in their excited states and the exchange of real photon is involved between them due t…
Observational constraints on sign-changeable interaction models and alleviation of the tension
Supriya Pan, Weiqiang Yang, Chiranjeeb Singha +1
We investigate various scenarios which include interaction forms between dark matter and dark energy that exhibit sign reverse, namely where the transfer of energy between the dark…
New coordinates for a simpler canonical derivation of the Hawking effect
Golam Mortuza Hossain, Chiranjeeb Singha
In order to achieve a Hamiltonian-based canonical derivation of the Hawking effect, one usually faces multiple hurdles. Firstly, the spacetime foliation using Schwarzschild time do…
Remarks on distinguishability of Schwarzschild spacetime and thermal Minkowski spacetime using Resonance Casimir-Polder interaction
Chiranjeeb Singha
One perceives same response of a single-atom detector when placed at a point outside the horizon in Schwarzschild spacetime to that of a static single-atom detector in thermal Mink…
An exact derivation of the Hawking effect in canonical formulation
Subhajit Barman, Golam Mortuza Hossain, Chiranjeeb Singha
The Hawking effect is one of the most extensively studied topics in modern physics. Yet it remains relatively under-explored within the framework of canonical quantization. The key…
