Effects of dipolar coupling on an entanglement storage device
Saptarshi Saha, Rangeet Bhattacharyya
Quantum computation requires efficient long-term storage devices to preserve quantum states. An attractive candidate for such storage devices is qubits connected to a common dissip…
Can a pure state remain pure in the Unruh effect?
Saptarshi Saha, Arpan Chatterjee, Chiranjeeb Singha
A uniformly accelerated detector in an inertial vacuum undergoes an unavoidable dissipation, and the final steady-state becomes thermal. However, to attain such a mixed state, ther…
Dissipative phase transition in a spatially-correlated bosonic bath
Saptarshi Saha, Rangeet Bhattacharyya
The presence of symmetries in a closed many-body quantum system results in integrability. For such integrable systems, complete thermalization does not occur. As a result, the syst…
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…
