| Abstract | |
We studied the single-particle momentum distribution of mass-imbalanced Efimov states embedded in noninteger dimensions. The contact parameters, which can be related to the thermodynamic properties of the gas, were extracted from the tail of the single-particle momentum densities. We studied the dependence of the contact parameters on the progressive change in the noninteger dimension, ranging from three (D = 3) to two (D = 2) dimensions. Within this interval, we move from the D = 3 regime where the Efimov discrete-scale symmetry drives the physics to close to the critical dimension, which depends on the mass imbalance, where the continuum-scale symmetry takes place. We found that the two- and three-body contacts grow significantly in magnitude with the decrease of the noninteger dimension towards the critical dimension, impacting observables of resonantly interacting trapped Bose gases.
