Controlling Rydberg atom excitations in dense background gases
Tara Cubel Liebisch, Michael Schlagmüller, Felix Engel +13
We discuss the density shift and broadening of Rydberg spectra measured in cold, dense atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating back…
Ultracold atom-electron interaction: from two to many-body physics
Anita Gaj, Alexander T. Krupp, Jonathan B. Balewski +3
The transition from a few-body system to a many-body system can result in new length scales, novel collective phenomena or even in a phase transition. Such a threshold behavior was…
Imaging single Rydberg electrons in a Bose-Einstein condensate
Tomasz Karpiuk, Mirosław Brewczyk, Kazimierz Rzążewski +7
The quantum mechanical states of electrons in atoms and molecules are distinct orbitals, which are fundamental for our understanding of atoms, molecules and solids. Electronic orbi…
Alignment of D-state Rydberg molecules
Alexander T. Krupp, Anita Gaj, Jonathan B. Balewski +6
We report on the formation of ultralong-range Rydberg D-state molecules via photoassociation in an ultracold cloud of rubidium atoms. By applying a magnetic offset field on the ord…
Rydberg dressing: Understanding of collective many-body effects and implications for experiments
Jonathan B. Balewski, Alexander T. Krupp, Anita Gaj +3
The strong interaction between Rydberg atoms can be used to control the strength and character of the interatomic interaction in ultracold gases by weakly dressing the atoms with a…
Coupling a single electron to a Bose-Einstein condensate
Jonathan B. Balewski, Alexander T. Krupp, Anita Gaj +5
The coupling of electrons to matter is at the heart of our understanding of material properties such as electrical conductivity. One of the most intriguing effects is that electron…
Förster interaction induced phase shift in a pair state interferometer
J. Nipper, J. B. Balewski, A. T. Krupp +3
We present experiments measuring an interaction induced phase shift of Rydberg atoms at Stark tuned Förster resonances. The phase shift features a dispersive shape around the reson…
An experimental and theoretical guide to strongly interacting Rydberg gases
Robert Löw, Hendrik Weimer, Johannes Nipper +4
We review experimental and theoretical tools to excite, study and understand strongly interacting Rydberg gases. The focus lies on the excitation of dense ultracold atomic samples…
Highly resolved measurements of Stark-tuned Förster resonances between Rydberg atoms
J. Nipper, J. B. Balewski, A. T. Krupp +3
We report on experiments exploring Stark-tuned Förster resonances between Rydberg atoms with unprecedented resolution in the Förster defect. The individual resonances are expected…
Lifetimes of ultralong-range Rydberg molecules in vibrational ground and excited state
Björn Butscher, Vera Bendkowsky, Johannes Nipper +7
Since their first experimental observation, ultralong-range Rydberg molecules consisting of a highly excited Rydberg atom and a ground state atom have attracted the interest in the…
Rydberg trimers and excited dimers bound by internal quantum reflection
V. Bendkowsky, B. Butscher, J. Nipper +8
Quantum reflection is a pure wave phenomena that predicts reflection of a particle at a changing potential for cases where complete transmission occurs classically. For a chemical…
