Confinement-induced unatomic trimer states

Quantum Gases 2024-08-06 v1

Abstract

The signature of an unatomic system is revealed by a continuous scale invariance that appears during a progressive dimensional squeezing of a resonantly interacting trimer. The unatomic regime is reached at the dimension D\overline D, which for three identical atoms is found to be D=2.292\overline D=2.292 - below this value, the trimer wave function at short distances displays a power-law behaviour. The fingerprint of this crossover is a sharp evolution of the contacts that characterizes the trimer momentum distribution tail.
