Designing Anisotropic Inflation with Form Fields

Understand

We study inflation with anisotropic hair induced by form fields.

• In four dimensions, the relevant form fields are gauge (one-form) fields and two-form fields.
• Assuming the exponential form of potential and gauge kinetic functions, we find new exact power-law solutions endowed with anisotropic hair.
• We also explore the phase space of anisotropic inflation and find fixed points corresponding to the exact power-law solutions.
