The discrete Efimov scaling behavior, well-known in the low-energy spectrum of three-body bound systems for large scattering lengths (unitary limit), is identified in the energy dependence of atom-molecule elastic cross-section in mass imbalanced systems. That happens in the collision of a heavy atom with mass $m_H$ with a weakly-bound dimer formed by the heavy atom and a lighter one with mass $m_L \ll m_H$. Approaching the heavy-light unitary limit the $s-$wave elastic cross-section $\sigma…

Discrete Scaling and Scattering Properties from Atom-Dimer Collision

A recent proposal on a new perspective to detect the Efimov-like discrete scaling in ultra-cold binary mixtures with strong mass-imbalanced atomic species is communicated. The discrete scaling can be

Limit cycles in the spectra of mass imbalanced many-boson system

The independence between few-body scales beyond the van der Waals universality is demonstrated for the extreme mass-imbalanced case of a specific many-boson system. This finding generalizes the

Cold-atom–dimer reaction rates with He4, Li6,7 , and Na23

Atom-dimer exchange and dissociation reaction rates are predicted for different combinations of two $^4$He atoms and one of the alkaline species among $^{6}$Li, $^{7}$Li and $^{23}$Na, by using

Laser-assisted self-induced Feshbach resonance for controlling heteronuclear quantum gas mixtures

We propose a new type of Feshbach resonance occurring when two different ultracold atoms in their ground state undergo an s-wave collision in the presence of a continuous-wave laser light. The atoms

Fixed-Point Few-Body Hamiltonians in Quantum Mechanics

We revisited how Weinberg’s ideas in Nuclear Physics influenced our own work and lead to a renormalization group invariant framework within the quantum mechanical few-body problem, and we also update

Heteronuclear Efimov Scenario with Positive Intraspecies Scattering Length.

TLDR
The three-body parameter at the three- body scattering threshold and the scaling factor between consecutive Efimov resonances are found to be controlled by the scattering length between the two bosons, approximately independent of short-range physics.

Avalanche-mechanism loss at an atom-molecule Efimov resonance

The avalanche mechanism has been used to relate Efimov trimer states to certain enhanced atom loss features observed in ultracold-atom-gas experiments. These atom loss features are argued to be a

Observation of Efimov resonances in a mixture with extreme mass imbalance.

We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture by measuring three-body loss coefficients as a function of magnetic field near a Feshbach resonance. The first

Atom-dimer and dimer-dimer scattering in fermionic mixtures near a narrow Feshbach resonance

Abstract We develop a diagrammatic approach for solving few-body problems in heteronuclear fermionic mixtures near a narrow interspecies Feshbach resonance. We calculate s-, p-, and d-wave

Tests of universal three-body physics in an ultracold bose-fermi mixture.

TLDR
It is found that an Efimov-like resonance is found in the rate of inelastic collisions between 40K87Rb Feshbach molecules and 87Rb atoms, however, any EFimov-related resonances are not observed in the rates of inelegant collisions between three atoms.

TLDR
The observation of three consecutive Efimov resonances in a heteronuclear Li-Cs mixture near a broad interspecies Feshbach resonance is reported.

Triatomic continuum resonances for large negative scattering lengths

We study triatomic systems in the regime of large negative scattering lengths which may be more favorable for the formation of condensed trimers in trapped ultracold monoatomic gases as the

TLDR
The results show good agreement with the theoretical model for the scattering dependent three-body recombination coefficient and reestablish universality across isotopic mixtures.
