Gravitational Waves from Post-Inflationary Magnetism: Direct and Scalar-Induced Contributions
Subhasis Maiti
We study stochastic gravitational waves generated in a post-inflationary magnetogenesis scenario with time-dependent gauge couplings during inflation and reheating. In this setup,…
Inflaton accretion onto primordial black holes during reheating
Jitumani Kalita, Debaprasad Maity
Primordial Black Holes (PBHs) forming prior to Big Bang Nucleosynthesis evolve during the reheating epoch, an environment dominated by an oscillating inflaton field decaying into a…
Cogenesis of visible and dark matter in type-I Dirac seesaw
Debasish Borah, Partha Kumar Paul, Narendra Sahu
We propose a novel cogenesis framework based on the type-I Dirac seesaw mechanism. The minimal type-I Dirac seesaw with three heavy vector-like fermions , one singlet scalar $…
Revisiting PBH accretion, evaporation and their cosmological consequences
Jitumani Kalita, Debaprasad Maity
Primordial black holes (PBHs) provide a unique probe of the early Universe. Their cosmological evolution is governed by the competition between mass accretion and Hawking evaporati…
Towards enhanced mixing of a high viscous miscible blob in porous media
Mijanur Rahaman, Jiten C. Kalita, Satyajit Pramanik
In this study, we investigate the rectilinear displacement and deformation of a highly viscous, miscible circular blob influenced by a less viscous fluid within a homogeneous porou…
Trust@Health: A Trust-Based Multilayered Network for Scalable Healthcare Service Management
Avijit Gayen, Somyajit Chakraborty, Joydeep Chakraborty +1
We study the intricate relationships within healthcare systems, focusing on interactions among doctors, departments, and hospitals. Leveraging an evolutionary graph framework, the…
