Momentum Distribution of a mass-imbalanced three-body system across the Efimov-Unatomic transition
D. S. Rosa, R. M. Francisco, T. Frederico +2
We investigate the single-particle momentum distribution, the two-body contact and three-body tail coefficients of mass-imbalanced three-body systems at the critical dimension $D_c…
Confinement-induced unatomic trimer states in mass-imbalanced systems
Rafael M. Francisco, D. S. Rosa, T. Frederico +2
As resonantly interacting trimers of the type AAB are progressively squeezed from to , unatomic states emerge. We calculated the contacts from the high momentum tail of…
Confinement-induced unatomic trimer states
D. S. Rosa, R. M. Francisco, T. Frederico +2
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 una…
Reliability of the Born-Oppenheimer approximation in noninteger dimensions
D. S. Rosa, T. Frederico, R. M. Francisco +2
We address the question of the reliability of the Born-Oppenheimer (BO) approximation for a mass-imbalanced resonant three-body system embedded in noninteger dimensions. We address…
Discrete scaling in non-integer dimensions
Tobias frederico, Rafael Mendes Francisco, Dérick dos Santos Rosa +2
We explore the effect of a finite two-body energy in the discrete scale symmetry regime of two heavy bosonic impurities immersed in a light bosonic system. By means of the Born-Opp…
