Remarks on brane-antibrane inflation
Gonzalo Villa
We provide an accessible review to the eta problem in brane-antibrane inflation and a recently proposed solution. The description of the antibrane by means of nonlinearly realized…

Cosmic (super)strings with a time-varying tension
Filippo Revello, Gonzalo Villa
Cosmic (super)strings offer promising ways to test ideas about the early universe and physics at high energies. While in field theory constructions their tension is usually assumed…
