Confinement-induced unatomic trimer states
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 $\overline{D}$, which for three identical atoms is found to be $\overline{D}=2.292$---below this value, the trimer wave function at short distances displays a power-law behavior. The fingerprint of this crossover is a sharp evolution of the contacts that characterizes the trimer momentum distribution tail.
