Inflation with exotic kinetic terms in Einstein-Chern-Simons gravity

Understand

An alternative scenario about the phenomenology of primordial Universe is k-inflation.

• According to this concept, inflation can be achieved by nonstandard kinetic term of scalar field, namely the inflaton.
• In this project we focus on k-essence models in the presence of a higher order and a linear kinetic term.
• Furthermore, the inflationary phenomenology with a Dirac-Born-Infeld scalar field is briefly examined, which arises from quantum theories of gravity such as superstring theory.
