Interaction between Physics and Cosmology
N. Panchapakesan
Recent results indicate the presence of a cosmological constant (or related dark energy) in the universe. It has been conjectured recently that the interaction parameters of physic…
Gravitational lensing constraint on the cosmic equation of state
Deepak Jain, Abha Dev, N. Panchapakesan +2
Recent redshift-distance measurements of Type Ia supernovae (SNe Ia) at cosmological distances suggest that two-third of the energy density of the universe is dominated by dark ene…
Constraints on the Cosmic Equation of State using Gravitational Lensing Statistics with evolving galaxies
Abha Dev, Deepak Jain, N. Panchapakesan +2
In this paper, observational constraints on the cosmic equation of state of dark energy () have been investigated using gravitational lensing statistics. A likelihood anal…
Constraints On Galaxy Evolution Through Gravitational Lensing Statistics
Deepak Jain, N. Panchapakesan, S. Mahajan +1
Explaining the formation and evolution of galaxies is one of the most challenging problems in observational cosmology. Many observations suggest that galaxies we see today could ha…
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…
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…
