String dynamics near a Kaluza-Klein black hole
H. K. Jassal, A. Mukherjee, R. P. Saxena
The dynamics of a string near a Kaluza-Klein black hole are studied. Solutions to the classical string equations of motion are obtained using the world sheet velocity of light as a…
Analytical approach to the transition to thermal hopping in the thin- and thick-wall approximations
Hatem Widyan, A. Mukherjee, N. Panchapakesan +1
The nature of the transition from the quantum tunneling regime at low temperatures to the thermal hopping regime at high temperatures is investigated analytically in scalar field t…
Baryogenesis from Primordial Blackholes after Electroweak Phase Transition
Niraj Upadhyay, Patrick Das Gupta, R. P. Saxena
Incorporating a realistic model for accretion of ultra-relativistic particles by primordial blackholes (PBHs), we study the evolution of an Einstein-de Sitter universe consisting o…
