One-Dimensional Quantum Systems - From Few to Many Particles
A. S. Dehkharghani
In this thesis, I go through the well-known solutions to the one and two-particle systems trapped in a quantum harmonic oscillator and then continue to the three, four and many-bod…
Integrable families of hard-core particles with unequal masses in a one-dimensional harmonic trap
N. L. Harshman, Maxim Olshanii, A. S. Dehkharghani +3
We show that the dynamics of particles in a one-dimensional harmonic trap with hard-core interactions can be solvable for certain arrangements of unequal masses. For any number of…
Quantum Simulation of Abelian Lattice Gauge Theories via State-Dependent Hopping
A. S. Dehkharghani, E. Rico, N. T. Zinner +1
We develop a quantum simulator architecture that is suitable for the simulation of Abelian gauge theories such as quantum electrodynamics. Our approach relies on the ability…
Comparing numerical and analytical approaches to strongly interacting two-component mixtures in one dimensional traps
F. F. Bellotti, A. S. Dehkharghani, N. T. Zinner
We investigate one-dimensional harmonically trapped two-component systems for repulsive interaction strengths ranging from the non-interacting to the strongly interacting regime fo…
Correlation properties of a three-body bosonic mixture in a harmonic trap
R. E. Barfknecht, A. S. Dehkharghani, A. Foerster +1
We make use of a simple pair correlated wave function approach to obtain results for the ground-state densities and momentum distribution of a one-dimensional three-body bosonic sy…
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…
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…
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…
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…
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…
