Contribution

It provides an analytical description of Efimov states under strong three-body losses, identifying conditions where decay rates vanish and energies become real.

Findings

Energies approach the positive real axis

Decay rates vanish in a specific regime

Analytical model of Efimov states with losses

Abstract

We determine analytically how Efimov trimer states are modified by three-body losses within the model of Braaten and Hammer. We find a regime where the energies approach the positive real axis and the decay rates vanish.
