Decay of baryon inhomogeneities in an expanding universe
Pratik K. Das, Sovan Sau, Abhisek Saha +1
Baryon inhomogeneities can be generated very early in the universe. These inhomogeneities then decay by particle diffusion in an expanding universe. We study the decay of these bar…

Neutrino currents in wakes of cosmic strings
Sovan Sau, Soma Sanyal
Neutrinos rotating around Abelian Higgs strings will generate a neutral current close to the string. As the string moves through the cosmic plasma, the velocity kick generated by t…

Diffusion coefficients and constraints on hadronic inhomogeneities in the early universe
Sovan Sau, Sayantan Bhattacharya, Soma Sanyal
Hadronic inhomogeneities are formed after the quark hadron phase transition. The nature of the phase transition dictates the nature of the inhomogeneities formed. Recently some sce…
