In this paper, we revisit the idea of locked inflation, which does not require a potential satisfying the normal slow-roll condition, but suffers from the problems associated with “saddle inflation”. We propose a scenario based on locked inflation, however, with an alternative evolution mechanism of the “waterfall field” φ. Instead of rolling down along the potential, the φ field will tunnel to end the inflation stage like in old inflation, by which the saddle inflation could be avoided… Expand
