Window for Efimov physics for few-body systems with finite-range interactions
S. E. Rasmussen, A. S. Jensen, D. V. Fedorov
We investigate the two lowest-lying weakly bound states of bosons as functions of the strength of two-body Gaussian interactions. We observe the limit for validity of Ef…
Quantum few-body bound states of dipolar particles in a helical geometry
J. K. Pedersen, D. V. Fedorov, A. S. Jensen +1
We study a quantum mechanical system consisting of up to three identical dipoles confined to move along a helical shaped trap. The long-range interactions between particles confine…
Occurrence conditions for two-dimensional Borromean systems
A. G. Volosniev, D. V. Fedorov, A. S. Jensen +1
We search for Borromean three-body systems of identical bosons in two dimensional geometry, i.e. we search for bound three-boson system without bound two-body subsystems. Unlike th…
Regularization of a three-body problem with zero-range potentials
D. V. Fedorov, A. S. Jensen
We propose a coordinate-space regularization of the three-body problem with zero-range potentials. We include the effective range and the shape parameter in the boundary condition…
Correlation induced collapse of many-body systems with zero-range potentials
D. V. Fedorov, A. S. Jensen
The zero-range potential is customarily employed in various mean-field calculations of many-body systems in atomic and nuclear physics within, correspondingly, Gross-Pitaevskii and…
