Anisotropic Constant-roll Inflation

arXiv:1710.09701 · doi:10.1140/epjc/s10052-018-5534-5

Abstract

We study constant-roll inflation in the presence of a gauge field coupled to an inflaton. By imposing the constant anisotropy condition, we find new exact anisotropic constant-roll inflationary solutions which include anisotropic power-law inflation as a special case. We also numerically show that the new anisotropic solutions are attractors in the phase space.
