(Gravitational Wave) Memory of Starobinsky in a Time Crystal (Condensate)
Aurindam Mondal, Subir Ghosh
In this Letter we have revealed the presence of Gravitational Wave Memory Effect (GWME) in a new and physically appealing scenario - the Time Crystal (TC) condensate of Starobinsky…

Gravitational Wave Propagation in a Geometric Condensate in Starobinsky Cosmology
Aurindam Mondal, Subir Ghosh
In this paper we propose a new paradigm for cosmology: a time dependent scalar condensate background originated from the quadratic Starobinski model, where is the…

Violation of Bell inequality from a squeezed coherent state of inflationary perturbations
Aurindam Mondal, Rathul Nath Raveendran
We investigate the quantum nature of primordial perturbations by studying the violation of Bell inequality when the initial state is taken to be a coherent state rather than the us…
