Analytic Solutions and Observational support: A study of gravity with
Akash Bose, Gopal Sardar, Subenoy Chakraborty
The present work deals with cosmological solutions in gravity theory for perfect fluid with constant equation of state (). For a viable cosmological solution is res…
Perturbative approach to the entanglement entropy and the area law in Fock and polymer quantization
Subhajit Barman, Gopal Sardar
The area dependence of entanglement entropy of a free scalar field is often understood in terms of coupled harmonic oscillators. In Schrodinger quantization, the Gaussian nature of…
Low Energy Lorentz Violation in Polymer Quantization Revisited
Nirmalya Kajuri, Gopal Sardar
In previous work, it had been shown that polymer quantized scalar field theory predicts that even an inertial observer can experience spontaneous excitations. This prediction was s…
Emergence of spacetime discreteness in Wightman function from polymer quantization of scalar field
Golam Mortuza Hossain, Gopal Sardar
The Wightman function i.e. vacuum two-point function, for a massless free scalar field in Fock quantization is inversely proportional to the invariant distance squared between the…
Transient response from Unruh-DeWitt detector along Rindler trajectory in polymer quantization
Golam Mortuza Hossain, Gopal Sardar
If an Unruh-DeWitt detector operates for an infinite proper time along the trajectory of a uniformly accelerated observer in Fock space then induced transition rate of the detector…
Violation of Kubo-Martin-Schwinger condition along a Rindler trajectory in polymer quantization
Golam Mortuza Hossain, Gopal Sardar
Existence of Unruh effect is often understood from the property of two-point function along Rindler trajectory where it satisfies KMS condition. In particular, it exhibits the so-c…
