Effects of thermal fluctuations on thermal inflation
Takashi Hiramatsu, Yuhei Miyamoto, Jun'ichi Yokoyama
The mechanism of thermal inflation, a relatively short period of accelerated expansion after primordial inflation, is a desirable ingredient for a certain class of particle physics…
Effects of cosmic strings with delayed scaling on CMB anisotropy
Kohei Kamada, Yuhei Miyamoto, Daisuke Yamauchi +1
The network of cosmic strings generated in a phase transition during inflation enters the scaling regime later than that of usual strings. If it occurs after the recombination, tem…
Langevin description of gauged scalar fields in a thermal bath
Yuhei Miyamoto, Hayato Motohashi, Teruaki Suyama +1
We study the dynamics of the oscillating gauged scalar field in a thermal bath. A Langevin type equation of motion of the scalar field, which contains both dissipation and fluctuat…
Evading the pulsar constraints on the cosmic string tension in supergravity inflation
Kohei Kamada, Yuhei Miyamoto, Jun'ichi Yokoyama
The cosmic string is a useful probe of the early Universe and may give us a clue to physics at high energy scales where any artificial particle accelerators cannot reach. Although…
