Nonexponential decay of Feshbach molecules
arXiv:1909.09614 · doi:10.1103/PhysRevA.101.013632
Abstract
We analyze the temporal behavior of the survival probability of an unstable Li Feshbach molecule close to the BCS-BEC crossover. We find different instances of nonexponential decay as the magnetic field approaches the resonance value, at which the molecule becomes stable. We observe a transition from an exponential decay towards a regime dominated by a stretched-exponential law.
