Accessibility Measure for Eternal Inflation: Dynamical Criticality and Higgs Metastability

Understand

We propose a new measure for eternal inflation, based on search optimization and first-passage statistics.

• This work builds on the dynamical selection mechanism for vacua based on search optimization proposed recently by the author and Parrikar.
• The approach is motivated by the possibility that eternal inflation has unfolded for a finite time much shorter than the exponentially long mixing time for the landscape.
• The proposed accessibility measure assigns greater weight to vacua that are accessed efficiently under time evolution.
