Few-boson dynamics in double wells: From single-atom to correlated-pair tunneling
Sascha Zöllner, Hans-Dieter Meyer, Peter Schmelcher
We investigate few-boson tunneling in a one-dimensional double well, covering the full crossover from weak interactions to the fermionization limit of strong correlations. Based on…
Quantum dynamics of two bosons in an anharmonic trap: Collective vs internal excitations
Christian Matthies, Sascha Zöllner, Hans-Dieter Meyer +1
This work deals with the effects of an anharmonic trap on an interacting two-boson system in one dimension. Our primary focus is on the role of the induced coupling between the cen…
Ultracold Rydberg Atoms in a Ioffe-Pritchard Trap
Bernd Hezel, Igor Lesanovsky, Peter Schmelcher
We discuss the properties of ultracold Rydberg atoms in a Ioffe-Pritchard magnetic field configuration. The derived two-body Hamiltonian unveils how the large size of Rydberg atoms…
Formation of Ultracold Heteronuclear Dimers in Electric Fields
Rosario González-Férez, Michael Mayle, Peter Schmelcher
The formation of ultracold molecules via stimulated emission followed by a radiative deexcitation cascade in the presence of a static electric field is investigated. By analyzing t…
One-dimensional Rydberg Gas in a Magnetoelectric Trap
Michael Mayle, Bernd Hezel, Igor Lesanovsky +1
We study the quantum properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap which is superimposed by a homogeneous electric field. Trapped Rydberg atoms can be created in l…
Spectral properties of a Rydberg atom immersed in a Bose-Einstein condensate
Stephan Middelkamp, Igor Lesanovsky, P. Schmelcher
The electronic spectrum of a Rydberg atom immersed in a Bose-Einstein condensate is investigated. The Heisenberg equations of motions for the condensate and the Rydberg atom are de…
