Cavity driven Rabi oscillations between Rydberg states of atoms trapped on a superconducting atom chip
Manuel Kaiser, Conny Glaser, Li Yuan Ley +8
Hybrid quantum systems involving cold atoms and microwave resonators can enable cavity-mediated infinite-range interactions between atomic spin systems and realize atomic quantum m…
Integrated and portable magnetometer based on nitrogen-vacancy ensembles in diamond
Felix M. Stürner, Andreas Brenneis, Thomas Buck +13
Magnetic field sensors that exploit quantum effects have shown that they can outperform classical sensors in terms of sensitivity enabling a range of novel applications in future,…
Absolute frequency measurement of rubidium 5S-6P transitions
Conny Glaser, Florian Karlewski, Jens Grimmel +4
We report on measurements on the 5S-6P rubidium transition frequencies for rubidium isotopes with an absolute uncertainty of better than \SI{450}{kHz} for the 5S 6P$_…
Controlling the dipole blockade and ionization rate of Rydberg atoms in strong electric fields
Markus Stecker, Raphael Nold, Lea-Marina Steinert +4
We study a novel regime of the Rydberg excitation blockade using highly Stark-shifted, yet long-living, states of Rb atoms subject to electric fields above the classical ionization…
Observation of the motional Stark shift in low magnetic fields
Manuel Kaiser, Jens Grimmel, Lara Torralbo-Campo +5
We report on the observation of the motional Stark effect of highly excited Rb Rydberg atoms moving in the presence of a weak homogeneous magnetic field in a vapor cell. Emp…
Ionization spectra of highly Stark shifted rubidium Rydberg states
Jens Grimmel, Markus Stecker, Manuel Kaiser +4
We report on the observation and numerical calculation of ionization spectra of highly Stark-shifted Rydberg states of rubidium beyond the classical ionization threshold. In the nu…
All-optical measurement of Rydberg state lifetimes
Markus Mack, Jens Grimmel, Florian Karlewski +3
We have developed an all-optical method for measuring the lifetimes of and Rydberg states and demonstrate its capabilities with measurements on a dilute cloud of ultrac…
Measurement and numerical calculation of Rubidium Rydberg Stark spectra
Jens Grimmel, Markus Mack, Florian Karlewski +4
We report on the measurement of Stark shifted energy levels of Rb Rydberg atoms in static electric fields by means of electromagnetically induced transparency (EIT). Electri…
State-selective all-optical detection of Rydberg atoms
Florian Karlewski, Markus Mack, Jens Grimmel +2
We present an all-optical protocol for detecting population in a selected Rydberg state of alkali atoms. The detection scheme is based on the interaction of an ensemble of ultracol…
Quasiclassical theory of quantum defect and spectrum of highly excited rubidium atoms
Ali Sanayei, Nils Schopohl, Jens Grimmel +3
We report on a significant discrepancy between recently published highly accurate variational calculations and precise measurements of the spectrum of Rydberg states in Rb o…
