Luminosity Selection for Gamma Ray Burst
Shreya Banerjee, Dafne Guetta
There exists an inevitable scatter in intrinsic luminosity of Gamma Ray Bursts(GRBs). If there is relativistic beaming in the source, viewing angle variation necessarily introduces…
Growth of Linear Perturbations in a Universe with Superfluid Dark Matter
Shreya Banerjee, Sayantani Bera, David F. Mota
The Lambda-Cold Dark Matter (LCDM) model agrees with most of the cosmological observations, but has some hindrances from observed data at smaller scales such as galaxies. Recently,…
Stability of charged particles inside a Paul trap with spontaneous localization dynamics
Sayantani Bera, Shreya Banerjee
Paul traps are ion traps that are widely used in spectroscopic experiments to confine and stabilize a charged particle within a small region using oscillating electric fields. The…
Evading the theoretical no-go theorem for nonsingular bounces in Horndeski/Galileon cosmology
Shreya Banerjee, Yi-Fu Cai, Emmanuel N. Saridakis
We show that a nonsingular bounce, free of ghosts and gradient instabilities, can be realized in the framework of Horndeski or generalized Galileon cosmology. In particular, we fir…
Bounce and cyclic cosmology in new gravitational scalar-tensor theories
Emmanuel N. Saridakis, Shreya Banerjee, R. Myrzakulov
We study the bounce and cyclicity realization in the framework of new gravitational scalar-tensor theories. In these theories the Lagrangian contains the Ricci scalar and its first…
The Minimum Distance of PPT Bound Entangled States from the Maximally Mixed State
Shreya Banerjee, Aryaman A. Patel, Prasanta K. Panigrahi
Using a geometric measure of entanglement quantification based on Euclidean distance of the Hermitian matrices, we obtain the minimum distance between a bipartite bound entangled $…
