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…
Simulation of Time-dependent Heisenberg Models in 1D
A. G. Volosniev, H. -W. Hammer, N. T. Zinner
In this paper, we provide a theoretical analysis of strongly interacting quantum systems confined by a time-dependent external potential in one spatial dimension. We show that such…
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 Impurity in a One-dimensional Trapped Bose Gas
A. S. Dehkharghani, A. G. Volosniev, N. T. Zinner
We present a new theoretical framework for describing an impurity in a trapped Bose system in one spatial dimension. The theory handles any external confinement, arbitrary mass rat…
