We present an inflationary model that is geodesically complete and does not suffer from the transplanckian problem. In most inflationary models, massless (conformal) scalar field f…

The cosmological BCS mechanism and the Big Bang Singularity
Stephon Alexander, Tirthabir Biswas
We provide a novel mechanism that resolves the Big Bang Singularity present in FRW space-times without the need for ghost fields. Building on the fact that a four-fermion interacti…

Superconducting loop quantum gravity and the cosmological constant
Stephon H. S. Alexander, Gianluca Calcagni
We argue that the cosmological constant is exponentially suppressed in a candidate ground state of loop quantum gravity as a nonperturbative effect of a holographic Fermi-liquid th…
