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…
Bounce solutions and the transition to thermal hopping in phi^4 theory with a phi^3 term
Hatem Widyan, A. Mukherjee, N. Panchapakesan +1
The nature of the transition from quantum tunneling at low temperatures to thermal hopping at high temperatures is investigated in a scalar field theory with cubic symmetry breakin…
Bubble formation in phi^4 theory in the thin-wall limit and beyond
Hatem Widyan, A. Mukherjee, N. Panchapakesan +1
Scalar field theory with an asymmetric potential is studied at zero temperature and high-temperature for phi^4 theory with both phi and phi^3 symmetry breaking. The equations of mo…
Duality and cosmological compactification of superstrings with unbroken supersymmetry
H. K. Jassal, A. Mukherjee, R. P. Saxena
The cosmological compactification of D=10, N=1 supergravity-super-Yang-Mills theory obtained from superstring theory is studied. The constraint of unbroken N=1 supersymmetry is imp…
