Non-Bunch-Davies Anisotropy
Xingang Chen, Yi Wang
We introduce a generic mechanism that can extend the effects of relic anisotropies at the beginning of inflation to relatively much shorter scales in density perturbations. This is…
Fluid Inflation
Xingang Chen, Hassan Firouzjahi, Mohammad Hossein Namjoo +1
In this work we present an inflationary mechanism based on fluid dynamics. Starting with the action for a single barotropic perfect fluid, we outline the procedure to calculate the…
A Single Field Inflation Model with Large Local Non-Gaussianity
Xingang Chen, Hassan Firouzjahi, Mohammad Hossein Namjoo +1
A detection of large local form non-Gaussianity is considered to be able to rule out all single field inflation models. This statement is based on a single field consistency condit…
