Relativistic quantum mechanics and quantum field theory
Urjit A. Yajnik
Relativistic quantum mechanics can be considered to have begun with a search for wave equations corresponding to each intrinsic spin. However, relativistic quantum physics differs…
Inflationary Gravitational Wave Spectral Shapes as test for Low-Scale Leptogenesis
Zafri A. Borboruah, Anish Ghoshal, Lekhika Malhotra +1
We study non-thermal resonant leptogenesis in a general setting where a heavy majoron decays to right-handed neutrinos (RHNs) whose further out-of-equilibrium decay generates t…
Gravitational production of massive scalars in the context of inflation
Urjit A. Yajnik
We set up a formalism for calculating the energy density generated in a quantized massive scalar field in the course of the drastic change in spacetime geometry at the end of the i…
Collider Signatures of boson in the Alternative Left-Right Model
Mariana Frank, Chayan Majumdar, Poulose Poulose +2
Alternative Left-Right Models offer an attractive option to left-right models. Emerging from grand unification, these models are consistent with light scalars which do not in…
Multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals
Himanshu Gaur, Urjit A. Yajnik
We study multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals. The Rényi entropy evaluation involves computing the partit…
Reheating constraints on modified quadratic chaotic inflation
Sudhava Yadav, Rajesh Goswami, K. K Venkataratnam +1
The Reheating era of inflationary universe can be parameterized by various parameters like reheating temperature \(T_{\text{re}}\), reheating duration \(N_{\text{re}}\) and average…
