Photogravitational processes
Jose F. Nieves, Palash B. Pal
In the linearized theory of gravity coupled to the electromagnetic field, we calculate the cross sections of two processes in which both the gravitational and electromagnetic inter…

A reincarnation of R-parity
Palash B. Pal
In supersymmetric theories, R-parity is defined in a way such that it does not commute with the space-time symmetries. We show that, in general sypersymmetric models, one can defin…

Functional derivation of Casimir energy at non-zero temperature
Avijit K. Ganguly, Palash B. Pal
Performing functional integration of the free Lagrangian, we find the vacuum energy of a field. The functional integration is performed in a way which easily generalizes to systems…
