Topological Defects in the Left-Right Symmetric Model and their Relevance to Cosmology
U. A. Yajnik, Hatem Widyan, Shobhit Mahajan +2
It is shown that the minimal left-right symmetric model admits cosmic string and domain wall solutions. The cosmic strings arise when the SU(2)_R is broken and can either be destab…
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…
Nucleosynthesis in a simmering univeerse
Daksh Lohiya, Annu Batra, Shobhit Mahajan +1
Primordial nucleosynthesis is considered a success story of the standard big bang (SBB) cosmology. The cosmological and elementary particle physics parameters are believed to be se…
Topological defects and conditions for baryogenesis in the Left-Right symmetric model
U. A. Yajnik, Hatem Widyan, Shobhit Mahajan +2
It is shown that the minimal Left-Right symmetric model admits cosmic string, domain wall and conditionally, monopole solutions. The strings arise when the is broken and…
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…
