Stability and dynamics of matter-wave vortices in the presence of collisional inhomogeneities and dissipative perturbations
S. Middelkamp, P. G. Kevrekidis, D. J. Frantzeskakis +2
In this work, the spectral properties of a singly-charged vortex in a In this work, the spectral properties of a singly-charged vortex in a Bose-Einstein condensate confined in a h…
Cold and Ultracold Rydberg Atoms in Strong Magnetic Fields
T. Pohl, H. R. Sadeghpour, P. Schmelcher
Cold Rydberg atoms exposed to strong magnetic fields possess unique properties which open the pathway for an intriguing many-body dynamics taking place in Rydberg gases consisting…
Magnetic trapping of ultracold Rydberg atoms in low angular momentum states
Michael Mayle, Igor Lesanovsky, Peter Schmelcher
We theoretically investigate the quantum properties of nS, nP, and nD Rydberg atoms in a magnetic Ioffe-Pritchard trap. In particular, it is demonstrated that the two-body characte…
Quantum dynamics of resonant molecule formation in waveguides
Vladimir S. Melezhik, Peter Schmelcher
We explore the quantum dynamics of heteronuclear atomic collisions in waveguides and demonstrate the existence of a novel mechanism for the resonant formation of polar molecules. T…
Magnetoconductance switching in an array of oval quantum dots
Christian Morfonios, Daniel Buchholz, Peter Schmelcher
Employing oval shaped quantum billiards connected by quantum wires as the building blocks of a linear quantum dot array, we calculate the ballistic magnetoconductance in the linear…
Evolutionary phase space in driven elliptical billiards
F. Lenz, C. Petri, F. N. R. Koch +2
We perform the first long-time exploration of the classical dynamics of a driven billiard with a four dimensional phase space. With increasing velocity of the ensemble we observe a…
