An interpolatory ansatz captures the physics of one-dimensional confined Fermi systems
M. E. S. Andersen, A. S. Dehkharghani, A. G. Volosniev +2
Interacting one-dimensional quantum systems play a pivotal role in physics. Exact solutions can be obtained for the homogeneous case using the Bethe ansatz and bosonisation techniq…
Tunable self-assembled spin chains of strongly interacting cold atoms
N. J. S. Loft, O. V. Marchukov, D. Petrosyan +1
We have developed an efficient computational method to treat long, one-dimensional systems of strongly-interacting atoms forming self-assembled spin chains. Such systems can be use…
Entanglement of an Impurity in a Few-Body One-Dimensional Ideal Bose System
M. A. García-March, A. S. Dehkharghani, N. T. Zinner
We study the correlation between an impurity and a small ensemble of bosonic particles in one dimension. Our study analyzes the one-body density matrix and calculates the correspon…
Impenetrable Mass-Imbalanced Particles in One-Dimensional Harmonic Traps
A. S. Dehkharghani, A. G. Volosniev, N. T. Zinner
Strongly interacting particles in one dimension subject to external confinement have become a topic of considerable interest due to recent experimental advances and the development…
Comparing models for the ground state energy of a trapped one-dimensional Fermi gas with a single impurity
N. J. S. Loft, L. B. Kristensen, A. E. Thomsen +1
We discuss the local density approximation approach to calculating the ground state energy of a one-dimensional Fermi gas containing a single impurity, and compare the results with…
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…
