Fermionic Dark Matter in Dynamical Scotogenic Model
Eung Jin Chun, Abhishek Roy, Sanjoy Mandal +1
In the Dynamical Scotogenic Model, the global symmetry is supposed to be broken spontaneously resulting in a massless Goldstone boson called majoron, and massive right handed…
WIMP and FIMP Dark Matter in Singlet-Triplet Fermionic Model
Geneviève Bélanger, Sandhya Choubey, Rohini M. Godbole +3
We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter. One triplet…
Entanglement in interacting quenched two-body coupled oscillator system
Sayantan Choudhury, Rakshit Mandish Gharat, Saptarshi Mandal +3
In this work, we explore the effects of a quantum quench on the entanglement measures of a two-body coupled oscillator system having quartic interaction. We use the invariant opera…
Krylov Complexity in Quantum Field Theory
Kiran Adhikari, Sayantan Choudhury, Abhishek Roy
In this paper, we study the Krylov complexity in quantum field theory and make a connection with the holographic "Complexity equals Volume" conjecture. When Krylov basis matches wi…
Four-mode squeezed states in de Sitter space: A study with two field interacting quantum system
Sayantan Choudhury, Sudhakar Panda, Nilesh Pandey +1
In this paper we study the application of four-mode squeezed states in the cosmological context, studying two weakly coupled scalar fields in the planar patch of the de Sitter spac…
Secluded Dark Matter in Gauged Model
Priyotosh Bandyopadhyay, Manimala Mitra, Rojalin Padhan +2
We consider the gauged model which is extended with a secluded dark sector, comprising of two dark sector particles. In this framework the lightest -odd partic…
