Ultra-long-range Rydberg molecules in crossed fields — •Markus Kurz1 and Peter Schmelcher1,2 — 1Zentrum für Optische Quantentechnologien, Universität Hamburg, Germany — 2Hamburg Centre for Ultrafast Imaging, Universität Hamburg, Germany
We investigate the impact of crossed external electric and magnetic fields on ultra-long-range Rydberg molecules [1] in the ultracold regime. The theoretical framework of the considered problem is based on the Fermi pseudopotential approximation, where in the electron perturber interaction p-wave contributions are included. This work concludes a number of previous studies where ultra-long-range Rydberg molecules had been exposed to electric and magnetic fields separated [2,3]. The rich topology of the Born-Oppenheimer potential surfaces for several field strengths is studied. Furthermore, we analyze the rovibrational dynamics for different electronically excited states. Finally, we present the electric and magnetic polarizability of field dressed high-ℓ molecular states for various field strengths.
