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…
Inflation and the Measurement Problem
Stephon Alexander, Dhrubo Jyoti, Joao Magueijo
We propose a solution to the quantum measurement problem in Inflation. Our model treats Fourier modes of cosmological perturbations as analogous to particles in a weakly-interactin…
Dynamics of Gauge Field Inflation
Stephon Alexander, Dhrubo Jyoti, Arthur Kosowsky +1
We analyze the existence and stability of dynamical attractor solutions for cosmological inflation driven by the coupling between fermions and a gauge field. Assuming a spatially h…
