Dynamically Generated Fermi Surface Mismatch and Relativistic Superfluidity in a Two-Component Massless Fermionic Theory
Susobhan Mandal, Sambuddha Sanyal
When fermions pair across mismatched Fermi surfaces, the mismatch reflects a built-in inequivalence between the species. We show it can instead arise dynamically by spontaneous sym…
Gyromagnetic ratio and Pauli form factor in anisotropic QED at one-loop
Susobhan Mandal, Subrata Mandal
The gyromagnetic ratio and Pauli form factor are important quantities that characterize the electric and magnetic moment distribution of a particle. The experimentally measured val…
Can Q-balls describe cosmological and galactic dark matter?
Susobhan Mandal, S. Shankaranarayanan
The Cold Dark Matter (CDM) hypothesis accurately predicts large-scale structure formation and fits the Cosmic Microwave Background temperature fluctuations (CMB). However, observat…
Generation of effective massive Spin-2 fields through spontaneous symmetry breaking of scalar field
Susobhan Mandal, S. Shankaranarayanan
General relativity and quantum field theory are the cornerstones of our understanding of physical processes, from subatomic to cosmic scales. While both theories work remarkably we…
Dynamical 4-D Gauss-Bonnet action from matter-graviton interaction at one-loop
Susobhan Mandal, S. Shankaranarayanan
The occurrence of singularities at the centers of black holes suggests that general relativity (GR), although a highly successful model of gravity and cosmology, is inapplicable. T…
Local description of S-matrix in quantum field theory in curved spacetime using Riemann-normal coordinate
Susobhan Mandal, Subhashish Banerjee
The success of the S-matrix in quantum field theory in Minkowski spacetime naturally demands the extension of the construction of the S-matrix in a general curved spacetime in a co…
Low-energy effective quantum field theoretic description of excitations about soliton configurations
Susobhan Mandal
Solitons are the classical field configurations connecting two trivial vacua. These are also the solutions of classical field equations of motion with particle-like properties. Mor…
Solitons in a class of interacting scalar field theories without invariance
Susobhan Mandal
In this article, we study kink soliton configurations in interacting scalar field theories containing two fields without invariance. We study a class of such theories, the…
Characteristics of Z(2) multi-kink soliton configurations
Susobhan Mandal
In this article, we first briefly review the solution of Z(2) kink solitons. Then we construct some multi-kink soliton configurations which are static and show their few features w…
