Two component WIMP-FImP dark matter model with singlet fermion, scalar and pseudo scalar
Amit Dutta Banik, Madhurima Pandey, Debasish Majumdar +1
We explore a two component dark matter model with a fermion and a scalar. In this scenario the Standard Model (SM) is extended by a fermion, a scalar and an additional pseudo scala…
Detecting phase boundaries of quantum spin-1/2 XXZ ladder via bipartite and multipartite entanglement transitions
Sudipto Singha Roy, Himadri Shekhar Dhar, Debraj Rakshit +2
Phase transition in quantum many-body systems inevitably causes changes in certain physical properties which then serve as potential indicators of critical phenomena. Besides the t…
Large Polarization Squeezing in Non-Degenerate Parametric Amplification of Coherent Radiation
Namrata Shukla, Ranjana Prakash
Polarization squeezing is shown to occur in non-degenerate parametric amplification of coherent light and the degree of squeezing at interaction time can be as large as $1-e^{-…
Relativistic sonic geometry for isothermal accretion in the Schwarzschild metric
Md Arif Shaikh, Ivleena Firdousi, Tapas K. Das
In this work, we perform linear perturbation on general relativistic isothermal accretion onto a non-rotating astrophysical black hole to study the salient features of the correspo…
Acoustic geometry obtained through the perturbation of the Bernoulli's constant
Satadal Datta, Md Arif Shaikh, Tapas K Das
For accretion onto astrophysical black holes, we demonstrate that linear perturbation of Bernoulli's constant defined for an inviscid irrotational adiabatic flow of perfect ideal f…
Exploring viable vacua of the -symmetric NMSSM
Jyotiranjan Beuria, Utpal Chattopadhyay, AseshKrishna Datta +1
We explore the vacua of the -symmetric Next-to-Minimal Supersymmetric Standard Model (NMSSM) and their stability by going beyond the simplistic paradigm that works with a tree…
