Simulating neural network criticality and resource dynamics with Rydberg gases
Patrick Mischke, Herwig Ott, Michael Fleischhauer +1
Efficient operation of neural networks has been linked to criticality in their underlying non-equilibrium excitation dynamics. However, obtaining experimental evidence of this conj…
All-optical measurement of magnetic fields for quantum gas experiments
Suthep Pomjaksilp, Sven Schmidt, Aaron Thielmann +2
We present an all-optical method to measure and compensate for residual magnetic fields present in a cloud of ultracold atoms trapped in an optical dipole trap. Our approach levera…
Engineering long-range molecular potentials by external drive
Tanita Klas, Jana Bender, Patrick Mischke +2
We report the engineering of molecular potentials at large interatomic distances. The molecular states are generated by off-resonant optical coupling to a highly excited, long-rang…
Anomalous excitation facilitation in inhomogeneously broadened Rydberg gases
Fabian Letscher, Oliver Thomas, Thomas Niederprüm +2
When atomic gases are laser driven to Rydberg states in an off resonant way, a single Rydberg atom may enhance the excitation rate of surrounding atoms. This leads to a facilitated…
Bistability vs. Metastability in Driven Dissipative Rydberg Gases
Fabian Letscher, Oliver Thomas, Thomas Niederprüm +2
We investigate the possibility of a bistable phase in an open many-body system. To this end we discuss the microscopic dynamics of a continuously off-resonantly driven Rydberg latt…
Rydberg molecule-induced remote spin-flips
Thomas Niederprüm, Oliver Thomas, Tanita Eichert +1
We have performed high resolution photoassociation spectroscopy of rubidium ultra long-range Rydberg molecules in the vicinity of the 25 state. Due to the hyperfine interaction…
Observation of pendular butterfly Rydberg molecules
Thomas Niederprüm, Oliver Thomas, Tanita Eichert +4
Obtaining full control over the internal and external quantum states of molecules is the central goal of ultracold chemistry and allows for the study of coherent molecular dynamics…
Giant cross section for molecular ion formation in ultracold Rydberg gases
Thomas Niederprüm, Oliver Thomas, Torsten Manthey +2
We have studied the associative ionization of a Rydberg atom and a ground state atom in an ultracold Rydberg gas. The measured scattering cross section is three orders of magnitude…
Mesoscopic Rydberg-blockaded ensembles in the superatom regime and beyond
T. M. Weber, M. Höning, T. Niederprüm +6
Controlling strongly interacting many-body systems enables the creation of tailored quantum matter, with properties transcending those based solely on single particle physics. Atom…
Continuous Coupling of Ultracold Atoms to an Ionic Plasma via Rydberg Excitation
T. M. Weber, T. Niederprüm, T. Manthey +4
We characterize the two-photon excitation of an ultracold gas of Rubidium atoms to Rydberg states analysing the induced atomic losses from an optical dipole trap. Extending the dur…
