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…

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…

A high resolution ion microscope for cold atoms
Markus Stecker, Hannah Schefzyk, József Fortágh +1
We report on an ion-optical system that serves as a microscope for ultracold ground state and Rydberg atoms. The system is designed to achieve a magnification of up to 1000 and a s…
