Abstract: The recently proposed trans-Planckian censorship conjecture (TCC) imposes a strong constraint on the inflationary Hubble scale, of which the upper bound could be largely relaxed by considering a noninstantaneous reheating history. In this paper we… read more here.

Abstract: We propose a more general version of the trans-Planckian censorship conjecture (TCC) which can apply to models of inflation with a varying speed of sound. We find that inflation models with cS read more here.

DOI: 10.1103/physrevd.102.021301
Abstract: We study the constraint on the inflationary energy scale from the recently proposed Trans-Planckian Censorship Conjecture (TCC). We find a universal upper bound on the inflationary Hubble expansion rate $H_\text{inf}$ which is solely determined by… read more here.
