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…
Multicomponent Strongly Interacting Few-Fermion Systems in One Dimension
Artem G. Volosniev, Dmitri V. Fedorov, Aksel S. Jensen +2
The paper examines a trapped one-dimensional system of multicomponent spinless fermions that interact with a zero-range two-body potential. We show that when the repulsion between…
Quantum single-particle properties in a one-dimensional curved space
J. K. Pedersen, D. V. Fedorov, A. S. Jensen +1
We consider one particle confined to a deformed one-dimensional wire. The quantum mechanical equivalent of the classical problem is not uniquely defined. We describe several possib…
Analytic solutions of topologically disjoint systems
J. R. Armstrong, A. G. Volosniev, D. V. Fedorov +2
We describe a procedure to solve an up to problem where the particles are separated topologically in groups with at most two particles in each. Arbitrary interactions are…
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…
