Cyclic cosmology from Cuscuton-Gallileons subjected to Lie point transformations

Biswajit Paul, Pushpendra Kumar Singh

Spacetime transformations in any physically viable theory should follow Lie Point symmetry. In this work, we explore the Cuscuton model extended to Galileons, as introduced by de R…

Measurement Incompatibility Based In-equivalence Between Bell and Network Nonlocality

Kaushiki Mukherjee, Biswajit Paul

It is a well-known fact that measurement incompatibility is a necessary resource to generate nonlocal correlations in usual Bell scenario that typically involves single quantum sou…

Uniform rate inflation in -gravity

Priyanka Mandal, B. C. Paul

We present uniform rate inflation in a modified gravity. It is found that early inflation can be realized even with a scalar field field with a quadratic poten…

-symmetry of Particle mixing theories and the equation of motion matrix

Kawaljeet Kaur, Biswajit Paul

A non-Hermitian complex scalar field model is considered from its $\mc{PT}$ symmetric aspect. A matrix constructed from the Euler-Lagrange equations of motion is utilized to analyz…
