چکیده
A few-body properties of spinless Bose particles interacting via the contact three-body potential in geometries with fractional dimensions $$1<d<2$$ are considered. We predict existence infinite tower Efimov bound states four-body sector at resonance. similar behavior is found five-body problem. It shown that ratio high-energy levels these two sectors a universal constant. The consequences emergence physics on many-body briefly discussed.

Origin of the three-body parameter universality in Efimov physics.
In recent years extensive theoretical and experimental studies of universal few-body physics have advanced our understanding of universal Efimov physics. Whereas theory had been the driving force behind our understanding of Efimov physics for decades, recent experiments have contributed an unexpected discovery. Specifically, measurements have found that the so-called three-body parameter determ...
متن کاملEfimov states with strong three-body losses
Introduction. – Motivated by nuclear physics, Efimov discovered that three particles with short-ranged two-body interactions of scattering length |a| = ∞ can support an infinite series of weakly bound trimer states [1]. In contrast to systems of nucleons or of He atoms, ultracold gases of alkali metal atoms offer the possibility to tune a by using a Feshbach resonance, and thus to go more deepl...

متن کاملEfimov Physics in Cold Atoms
Atoms with a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interactions at short distances. In the 2-atom sector, the universal properties are familiar and depend only on the scattering length. In the 3-atom sector for identical bosons, the universal properties include the existence of a sequence of shallow triatomic m...
متن کاملEfimov effect in nuclear three-body resonance decays.
We investigate the effects of the nearly fulfilled Efimov conditions on the properties of three-body resonances. Using the hyper-spheric adiabatic expansion method we compute energy distributions of fragments in a three-body decay of a nuclear resonance. As a realistic example we investigate the 1- state in the halo nucleus 11Li within a three-body model 9Li + n +n model. Characteristic feature...
