A non-local origin for massive gravity and late-time acceleration
Susobhan Mandal, S. Shankaranarayanan
The accelerated expansion of the universe poses a significant challenge to General Relativity. Non-local modifications to gravity have emerged as a compelling class of theories to…
Thermal field theories coupled to curved spacetime
Susobhan Mandal
Thermal field theory is an essential tool for comprehending various physical phenomena, including astrophysical objects such as neutron stars and white dwarfs, as well as the early…
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…
Quantum signatures in black hole accretion: Pair production in dynamical magnetic fields
Susobhan Mandal, Tausif Parvez, S. Shankaranarayanan
Accretion disks around black holes host extreme conditions where general relativity and magnetohydrodynamics dominate. These disks exhibit two distinct dynamical regimes -- Standar…
Modified theories of gravity at different curvature scales
Susobhan Mandal, S. Shankaranarayanan
General Relativity (GR) remains the cornerstone of gravitational physics, providing remarkable success in describing a wide range of astrophysical and cosmological phenomena. Howev…
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…
