Gravitational Particle Creation in a Stiff Matter Dominated Universe
- Physics
- 2017
A scenario for gravitational particle creation in a stiff matter dominated flat Friedmann-Robertson-Walker universe is presented. The primary creation of scalar particles is calculated using quantum…
Casimir effect of two conducting parallel plates in a general weak gravitational field
- Physics
- 2015
We calculate the finite vacuum energy density of the scalar and electromagnetic fields inside a Casimir apparatus made up of two conducting parallel plates in a general weak gravitational field. The…
On the time-dependent Rindler Hamiltonian single particle eigenstates in momentum space
- Physics
- 2020
We have developed a formalism in the non-relativistic scenario to obtain the time evolution of the eigenstates of Rindler Hamiltonian in momentum space. Hence, the particle wave function in spaceti...
Time Dependent Rindler Hamiltonian Eigen States in Momentum Space.
- Physics
- 2016
We have developed a formalism to get the time evolution of the eigen states of Rindler Hamiltonian in momentum space. We have shown the difficulties with characteristic curves, and re-cast the time…
Causal set as a discretized phase spacetime
- Philosophy
- 2009
The first goal of this paper is to show that discreteness, locality, and relativistic covariance can peacefully coexist if the ordinary spacetime (OST) is replaced with phase spacetime (PST) as a…
Do static sources respond to massive scalar particles from the Hawking radiation as uniformly accelerated ones do in the inertial vacuum
- Physics
- 2003
We examine the recently found equivalence for the response of a static scalar source interacting with a massless Klein-Gordon field when the source is ~i! static in Schwarzschild spacetime, in the…
Experimental evidence for radiation reaction thermalized at the Fulling-Davies-Unruh temperature
- Physics
- 2019
We examine the radiation reaction imparted on an electron accelerating and radiating in an optical medium. The radiation reaction of the electron is incorporated by modeling it as an Unruh-DeWitt…
Dynamics of atom mirrors and Casimir effect
- Physics
- 2018
We describe the atom mirrors in terms of a derivative-coupling Unruh-DeWitt harmonic-oscillator detector theory in (1+1) dimensions. Without introducing the Dirichlet boundary condition to the field,…
Particle decay in expanding Friedmann-Robertson-Walker universes
- Physics
- 2018
The lack of energy conservation introduces new particle processes in curved spacetime that are forbidden in flat space. Therefore one has to be very cautious about using the results calculated in…
