Distributed vorticity model for vortex molecule dynamics
Sarthak Choudhury, Joachim Brand
We analyze the effect of a hard wall trapping potential on the dynamics of a vortex molecule in a two-component Bose-Einstein condensate with linear coherent coupling. A vortex mol…
Andreev bound states at boundaries of polarized 2D Fermi superfluids with s-wave pairing and spin-orbit coupling
Kadin Thompson, Joachim Brand, Ulrich Zülicke
A topological superfluid phase characterized by an emergent chiral-p-wave pair potential is expected to form in a two-dimensional Fermi superfluid subject to s-wave pairing, spin-o…
Rotational pendulum dynamics of a vortex molecule in a channel geometry
Sarthak Choudhury, Joachim Brand
A vortex molecule is a topological excitation in two coherently coupled superfluids consisting of a vortex in each superfluid connected by a domain wall of the relative phase, also…
Magnetic impurity in a one-dimensional few-fermion system
Lukas Rammelmüller, David Huber, Matija Čufar +3
We present a numerical analysis of spin- fermions in a one-dimensional harmonic potential in the presence of a magnetic point-like impurity at the center of the trap.…
Polaron-Depleton Transition in the Yrast Excitations of a One-Dimensional Bose Gas with a Mobile Impurity
Mingrui Yang, Matija Čufar, Elke Pahl +1
We present exact numerical data for the lowest-energy momentum eigenstates (yrast states) of a repulsive spin impurity in a one-dimensional Bose gas using full configuration intera…
Triplet character of 2D-fermion dimers arising from -wave attraction via spin-orbit coupling and Zeeman splitting
Ulrich Ebling, Ulrich Zülicke, Joachim Brand
We theoretically study spin- fermions confined to two spatial dimensions and experiencing isotropic short-range attraction in the presence of both spin-orbit coupling and Zeem…
