Anisotropic Inflation from Charged Scalar Fields
Anisotropic Inflation Charged Scalar Fields
2011/1/11
We consider models of inflation with $U(1)$ gauge fields and charged scalar fields including symmetry breaking potential, chaotic inflation and hybrid inflation. We show that there exist attractor sol...
The Nature of Primordial Fluctuations from Anisotropic Inflation
Primordial Fluctuations Anisotropic Inflation
2010/3/9
We study the statistical nature of primordial fluctuations from an anisotropic inflation which is realized by a vector field coupled to an inflaton. We find a suitable gauge, which we call the canonic...
Scalar-Scalar, Scalar-Tensor, and Tensor-Tensor Correlators from Anisotropic Inflation
Scalar-Tensor Scalar-Scalar Tensor-Tensor Anisotropic Inflation
2010/3/22
We compute the phenomenological signatures of a model (Watanabe et al' 09) of anisotropic inflation driven by a scalar and a vector field. The action for the vector is U(1) invariant, and the model is...
