Title: Primordial anisotropies and asymmetries during inflation
Date (JST): Wed, Jul 27, 2016, 13:30 - 14:30
Place: Seminar Room A
Abstract: In this talk we review some mechanisms to generate primordial statistical anisotropies and asymmetries in models of inflation. We investigate asymmetries and inhomogeneities generated by primordial defects such as domain wall and massive monopole present during inflation. In addition, we present an effective field theory description of anisotropic inflation based on U(1) gauge fields and calculate the anisotropic power spectrum.
