Few-body Bose gases in low dimensions -- a laboratory for quantum dynamics
S. I. Mistakidis, A. G. Volosniev, R. E. Barfknecht +5
Cold atomic gases have become a paradigmatic system for exploring fundamental physics, which at the same time allows for applications in quantum technologies. The accelerating deve…
State transfer in an inhomogeneous spin chain
Michael Iversen, Rafael Emilio Barfknecht, Angela Foerster +1
We present an analytical study of state transfer in a spin chain in the presence of an inhomogeneous set of exchange coefficients. We initially consider the homogeneous case and de…
Effects of interaction imbalance in a strongly repulsive one-dimensional Bose gas
R. E. Barfknecht, A. Foerster, N. T. Zinner
We calculate the spatial distributions and the dynamics of a few-body two-component strongly interacting Bose gas confined to an effectively one-dimensional trapping potential. We…
Emergence of junction dynamics in a strongly interacting Bose mixture
Rafael E. Barfknecht, Angela Foerster, Nikolaj T. Zinner
We study the dynamics of a one-dimensional system composed of a bosonic background and one impurity in single- and double-well trapping geometries. In the limit of strong interacti…
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…
A geometric wave function for few interacting bosons in a harmonic trap
B. Wilson, A. Foerster, C. C. N. Kuhn +2
We establish a new geometric wave function that combined with a variational principle efficiently describes a system of bosons interacting in a one-dimensional trap. By means of a…
Phase Diagrams of Three-Component Attractive Ultracold Fermions in One-Dimension
C. C. N. Kuhn, A. Foerster
We investigate trions, paired states and quantum phase transitions in one-dimensional SU(3) attractive fermions in external fields by means of the Bethe ansatz and the dressed ener…
