Open-source library for performance-portable neutrino reaction rates: Application to neutron star mergers

Leonardo Chiesa, Maitraya Bhattacharyya, Filippo Mazzini +3

A realistic and detailed description of neutrinos in binary neutron star (BNS) mergers is essential to build reliable models of such systems. To this end, we present BNS_NURATES, a…

Analytical and numerical treatment of perturbed black holes in horizon-penetrating coordinates

Maitraya K Bhattacharyya, David Hilditch, K Rajesh Nayak +2

The deviations of non-linear perturbations of black holes from the linear case are important in the context of ringdown signals with large signal-to-noise ratio. To facilitate a co…

A method for obtaining nonspreading solutions of the Schrödinger equation

Tamoghna Majumdar, Maitraya Kanta Bhattacharyya, Kumble Rajesh Nayak

In this paper, we present a simple analytical method for obtaining a nonspreading solution of the time-dependent Schrödinger equation, which is given by the Airy function. The solu…
