Shortest nonzero lattice points in a totally real multi-quadratic number field and applications
Jishu Das
Let be a multi-quadratic totally real number field. Let denote its distinct embeddings. Given we give an explicit formula for and $\sum_…
Investigating the effects of gravitational lensing by Hu-Sawicki gravity black holes
Gayatri Mohan, Nashiba Parbin, Umananda Dev Goswami
In this work, gravitational lensing in the weak and strong field limits is investigated for black hole spacetime within the framework of Hu-Sawicki gravity. We employ the Is…
Weak asymptotic solution of one dimensional zero pressure dynamics system in the quarter plane
Kayyunnapara Divya Joseph
In this paper we study a system of equations which appear in the modelling of many physical phenomena. Initially this system appeared in description of the large scale structure fo…
Wave Interaction For A System In Elastodynamics With Initial Data Lying On The Level Set Of One Of The Riemann Invariants
Kayyunnapara Divya Joseph
This paper is concerned with the study of interaction of waves originating from the Riemann problem centred at two different points for a system of equations modelling propagation…
A lower bound for classical Kloosterman sums and an application
Stephan Baier, Jishu Das, Jewel Mahajan
We present a lower bound for the classical Kloosterman sum where and is an odd integer. We apply this lower bound for Kloosterman sums to derive an explic…
Few-Photon Fluorescence from Ultracold Bosons in an Optical Cavity
Megha Gopalakrishna, Emil Viñas Boström, Claudio Verdozzi
Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second-harmonic generation (SHG) regimes. Two settings ar…
