Squeezing the Efimov effect
(2018-02-28)
The quantum mechanical three-body problem is a source of continuing interest due to its complexity and not least due to the presence of fascinating solvable cases. The prime example is the Efimov effect where infinitely ...
Efimov effect in a D-dimensional Born-Oppenheimer approach
(2019-01-28)
We study a three-body system, formed by two identical heavy bosons and a light particle, in the Born-Oppenheimer approximation for an arbitrary dimension D. We restrict D to the interval 2 < D < 4, and derive the heavy-heavy ...
Efimov state predictions for He2-X triatomic systems
(2001-03-12)
A scale independent approach that was proposed in [1], valid for weakly bound three-boson systems, is used to predict that the three-body molecular system 4He2-7Li supports an Efimov state [2] with binding energy close to 2.31 mK.
Neutron-C-19 scattering near an Efimov state
(Elsevier B.V., 2008-12-04)
The low-energy neutron-C-19 scattering in a neutron-neutron-core model is studied with large scattering lengths near the conditions for the appearance of an Efimov state. We show that the real part of the elastic s-wave ...
Brunnian and Efimov N-Body States
(Springer Wien, 2011-11-01)
The Efimov effect was originally formulated for three particles. The underlying principle of model independence is extended in this article in several directions. We present our definitions of the concepts of universality ...

Dimensional Effects in Efimov Physics
(2019-06-01)
Efimov physics is drastically affected by the change of spatial dimensions. Efimov states occur in a tridimensional (3D) environment, but disappear in two (2D) and one (1D) dimensions. In this paper, dedicated to the memory ...

Universal aspects of Efimov states and light halo nuclei
(1997-11-01)
The parametric region in the plane defined by the ratios of the energies of the subsystems and the three-body ground state, in which Efimov states can exist, is determined. We use a renormalizable model that guarantees the ...
