Impurities in a one-dimensional Bose gas: the flow equation approach
F. Brauneis, H. -W. Hammer, M. Lemeshko +1
A few years ago, flow equations were introduced as a technique for calculating the ground-state energies of cold Bose gases with and without impurities. In this paper, we extend th…
Clusters in Separated Tubes of Tilted Dipoles
Jeremy R. Armstrong, Aksel S. Jensen, Artem G. Volosniev +1
A few-body cluster is a building block of a many-body system in a gas phase provided the temperature at most is of the order of the binding energy of this cluster. Here we illustra…
Induced correlations between impurities in a one-dimensional quenched Bose gas
S. I. Mistakidis, A. G. Volosniev, P. Schmelcher
We explore the time evolution of two impurities in a trapped one-dimensional Bose gas that follows a change of the boson-impurity interaction. We study the induced impurity-impurit…
In-medium bound states of two bosonic impurities in a one-dimensional Fermi gas
D. Huber, H. -W. Hammer, A. G. Volosniev
We investigate the ground-state energy of a one-dimensional Fermi gas with two bosonic impurities. We consider spinless fermions with no fermion-fermion interactions. The fermion-i…
Universal physics of bound states of a few charged particles
C. H. Schmickler, H. -W. Hammer, A. G. Volosniev
We study few-body bound states of charged particles subject to attractive zero-range/short-range plus repulsive Coulomb interparticle forces. The characteristic length scales of th…
A Solvable Model for Decoupling of Interacting Clusters
Artem G. Volosniev, Aksel S. Jensen, Nathan L. Harshman +2
We consider M clusters of interacting particles, whose in-group interactions are arbitrary, and inter-group interactions are approximated by oscillator potentials. We show that the…
