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…
