Parametric Resonance and Backreaction Effects in Magnetogenesis from Ultralight Dark Matter
Nirmalya Brahma, Robert Brandenberger
We take a more detailed look at the recently proposed magnetogenesis mechanism triggered by ultralight dark matter coupled to electromagnetism. The proposed mechanism made use of a…
Resonant axion and dark photon production in magnetic white dwarfs
Nirmalya Brahma, Ella Iles, Hugo Schérer +1
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In…
Photon conversion to axions and dark photons in magnetized plasmas: a finite-temperature field theory approach
Nirmalya Brahma, Katelin Schutz
Some of the most stringent constraints on physics beyond the Standard Model (BSM) arise from considerations of particle emission from astrophysical plasmas. However, many studies a…
Photon-Dark Photon Conversion with Multiple Level Crossings
Nirmalya Brahma, Asher Berlin, Katelin Schutz
Dark photons can oscillate into Standard Model (SM) photons via kinetic mixing. The conversion probability depends sensitively on properties of the ambient background, such as the…
Resonant Pseudo-Dirac Dark Matter as a Sub-GeV Thermal Target
Nirmalya Brahma, Saniya Heeba, Katelin Schutz
Dark matter (DM) could be a pseudo-Dirac thermal relic with a small mass splitting that is coupled off-diagonally to a kinetically mixed dark photon. This model, particularly in th…
A Large- Phase Transition in a Finite Lattice Gauge Theory
Nirmalya Brahma, Chethan Krishnan
We consider gauge theories of non-Abelian groups, and discuss the 1+1 dimensional lattice gauge theory of the permutation group as an illustrative example. The parti…
Analytical Computation of Cosmological Correlators from Symmetries and Singularities
Nirmalya Brahma
Cosmological correlators are very important objects in cosmology as they offer us a huge amount of information of the early universe. They reside on the future boundary of a de Sit…
Energy injection in pre-recombination era and EDGES detection
Nirmalya Brahma, Shiv Sethi, Shivnag Sista
We study the possibility of explaining the recent EDGES detection by an energy injection in the pre-recombination era. Our aim is to show that the residue of this energy injection…
