Interaction of exact gravitational waves with matter
Morteza Mohseni, Saurya Das
We consider interactions of exact (i.e., solutions of full nonlinear field equations) gravitational waves with matter by using the Einstein-Boltzmann equation. For a gravitational…
Power-Law Bounces in Gravity: Analysis of the Ekpyrosis and Accelerating Regimes
Saurya Das, Peter Dunsby, S. Shajidul Haque +1
We investigate the dynamics of the Friedmann-Lemaître-Robertson-Walker spacetime within the framework of gravity using a compact, model-independent dynamical systems approac…
Testing the Quantum Equivalence Principle with Gravitational Waves
Saurya Das, Mitja Fridman, Gaetano Lambiase
We study modifications of gravitational wave observables, such as the wave amplitude and frequency, which follow from the quantum equivalence principle, and are expressed in terms…
Test of Quantum Gravity in Optical Magnetometers
Mitja Fridman, James Maldaner, Gil Porat +1
In this work, quantum gravity effects, which can potentially be measured in magnetometers through the Larmor frequency of atoms in an external magnetic field, are estimated. It is…
