Quintessence and Inflation from Symmetry Breaking Transition of the Internal Manifold
Tirthabir Biswas, Prashanth Jaikumar
We show that even in the simple framework of pure Kaluza-Klein gravity the shape moduli can generate potentials supporting inflation and/or quintessence. Using the shape moduli as…
A Hagedorn temperature in post-inflationary dynamics?
Prashanth Jaikumar, Anupam Mazumdar
We consider the possibility of regarding the maximum temperature $\tm$ of a plasma of inflaton decay products as a Hagedorn temperature connected with the transition from an inflat…
Neutrino Bremsstrahlung in Neutron Matter from Effective Nuclear Interactions
A. Schwenk, P. Jaikumar, C. Gale
We revisit the emissivity from neutrino pair bremsstrahlung in neutron-neutron scattering, nn -> nn nu nubar, which was calculated from the one-pion exchange potential including co…
Ultra-high energy cosmic rays, cosmological constant, and -vacua
Prashanth Jaikumar, Anupam Mazumdar
We propose that the origin of ultra-high energy cosmic rays beyond the GZK cutoff and the origin of small cosmological constant can both be explained by vacuum tunneling effects in…
