Belle II Constraints on the Non-Minimal Universal Extra Dimensional Model
Avirup Shaw
Recent measurements by the Belle II Collaboration report a branching ratio for the decay with a 3.5 significance and deviating by 2.7 from Standard Mo…
Discrete time crystal order in spin chains enabled by Floquet flat bands
Mahbub Rahaman, Analabha Roy
We propose a novel protocol to realize discrete time-crystal (DTC) order in clean, periodically driven spin- chains. In each drive cycle, a global spin flip is followed by a t…
A Brief Study of Dark Energy Accretion onto Schwarzschild Black Hole : Biswas-Roy-Biswas Type Redshift Parameterization is Chosen
Subhajit Pal, Sukanya Dutta, Ritabrata Biswas
In this letter, we have considered accretion of a particular type of Dark Energy model onto a Schwarzschild type black hole. Before using the model, the free parameters of the Dark…
Stability Analysis of Four Gravity Models : A Cosmological Review in the Background of Bianchi-I Anisotropy
Subhajit Pal, Atanu Mukherjee, Ritabrata Biswas +1
With the non-metricity scalar as the functional argument, several gravity models are found to be proposed which are perfectly able to mimic the late-time accelerated exp…
