A variational approach to repulsively interacting three-fermion systems in a one-dimensional harmonic trap
N. J. S. Loft, A. S. Dehkharghani, N. P. Mehta +2
We study a three-body system with zero-range interactions in a one-dimensional harmonic trap. The system consists of two spin-polarized fermions and a third particle which is disti…
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…
Quantum magnetism in strongly interacting one-dimensional spinor Bose systems
A. S. Dehkharghani, A. G. Volosniev, E. J. Lindgren +5
Strongly interacting one-dimensional quantum systems often behave in a manner that is distinctly different from their higher-dimensional counterparts. When a particle attempts to m…
Repulsively interacting fermions in a two-dimensional deformed trap with spin-orbit coupling
O. V. Marchukov, D. V. Fedorov, A. S. Jensen +2
We investigate a two-dimensional system of with two values of the internal (spin) degree of freedom. It is confined by a deformed harmonic trap and subject to a Zeeman field, Rashb…
Hyperspherical Treatment of Strongly-Interacting Few-Fermion Systems in One Dimension
A. G. Volosniev, D. V. Fedorov, A. S. Jensen +1
We examine a one-dimensional two-component fermionic system in a trap, assuming that all particles have the same mass and interact through a strong repulsive zero-range force. Firs…
Engineering the Dynamics of Effective Spin-Chain Models for Strongly Interacting Atomic Gases
A. G. Volosniev, D. Petrosyan, M. Valiente +3
We consider a one-dimensional gas of cold atoms with strong contact interactions and construct an effective spin-chain Hamiltonian for a two-component system. The resulting Heisenb…
Statistical properties of spectra in harmonically trapped spin-orbit coupled systems
O. V. Marchukov, A. G. Volosniev, D. V. Fedorov +2
We compute single-particle energy spectra for a one-body hamiltonian consisting of a two-dimensional deformed harmonic oscillator potential, the Rashba spin-orbit coupling and the…
Spin-Orbit Coupling in Deformed Harmonic Traps
Oleksandr V. Marchukov, Artem G. Volosniev, Dmitri V. Fedorov +2
We consider a two-dimensional system of harmonically trapped particles with pseudo-spin- degree of freedom. This degree of freedom is coupled to the particle's momentu…
