N-body Efimov states from two-particle noise

Understand

The ground state energies of universal N-body clusters tied to Efimov trimers, for N even, are shown to be encapsulated in the statistical distribution of two particles interacting with a background auxiliary field at large Euclidean time when the interaction is tuned to the unitary point.

• Numerical evidence that this distribution is log-normal is presented, allowing one to predict the ground-state energies of the N-body system.
