Charged Vector Inflation
Hassan Firouzjahi, Mohammad Ali Gorji, Seyed Ali Hosseini Mansoori +2
We present a model of inflation in which the inflaton field is charged under a triplet of gauge fields. The model enjoys an internal symmetry supporting the isotropic…
Gauge Field Mimetic Cosmology
Mohammad Ali Gorji, Shinji Mukohyama, Hassan Firouzjahi +1
We extend the mimetic cosmology to models containing gauge invariant -forms. The -form case reproduces the well-known results of the mimetic dark matter, the -form corresp…
Two-field disformal transformation and mimetic cosmology
Hassan Firouzjahi, Mohammad Ali Gorji, Seyed Ali Hosseini Mansoori +2
We extend the disformal transformation to models with two scalar fields and look at its singular limit. Solving the eigentensor equation for the Jacobian of the transformation of t…
