Cosmic Time Slip: Testing Gravity on Supergalactic Scales with Strong-Lensing Time Delays
Dhrubo Jyoti, Julian B. Munoz, Robert R. Caldwell +1
We devise a test of nonlinear departures from general relativity (GR) using time delays in strong gravitational lenses. We use a phenomenological model of gravitational screening a…

Dipolarly-Coupled Chaotic Quantum Spin Systems
Dhrubo Jyoti
We numerically study quantum chaos properties of long-range XXZ dipolar Hamiltonian spin systems. Two geometries are considered: (i) an open chain with 19 spins, (ii) a face-center…
