Finite-Momentum Kinetic Corrections to Viscous Tensor Perturbations in an Expanding Universe
Nishil Savla, Gurudatt Gaur
We study tensor perturbations propagating through a viscous relativistic medium in a spatially flat FLRW universe, with particular emphasis on the correction produced by spatial fr…

Classical Reconstruction of the PMNS Matrix Using a Mechanical Neutrino Oscillator
Nishil Savla
Neutrino oscillations arise from quantum interference between neutrino mass eigenstates and are governed by the PMNS matrix. Although this is an intrinsically quantum phenomenon, i…
