Curvature Perturbations and non-Gaussianities from Waterfall Phase Transition during Inflation
Curvature Perturbations non-Gaussianities
2011/1/13
We consider a variant of hybrid inflation where the waterfall phase transition happens during inflation. By adjusting the parameters associated with the mass of the waterfall field, we arrange that t...
Imprints of the QCD Phase Transition on the Spectrum of Gravitational Waves
the QCD Phase Transition the Spectrum
2011/1/10
We have investigated effects of the QCD phase transition on the relic GW spectrum applying several equations of state for the strongly interacting matter: Besides the bag model, which describes a firs...
Pasta Structures of Quark-Hadron Phase Transition in Proto-Neutron Stars
Pasta Structures Quark-Hadron Phase Transition
2011/1/11
We study the quark-hadron mixed phase in proto-neutron stars with the finite-size effects. In the calculations of pasta structures appeared in the mixed phase, the Gibbs conditions require the pressur...
The revival of an explosion mechanism of massive stars - the quark hadron phase transition during the early post bounce phase of core collapse supernovae
Core collapse supernovae protoneutron stars general relativity radiation hydrodynamics
2010/11/16
We explore explosions of massive stars, which are triggered via the quark hadron phase transition during the early post bounce phase of core collapse supernovae. The onset of quark matter is favored u...
Phase transition to the state with nonzero average helicity in dense neutron matter
Phase transition nonzero average dense neutron matter
2010/11/16
The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model with the Skyrme effective interaction. By providing the analysis of the selfco...
