To facilitate the transition of quantum effects from the controlled laboratory environment to practical real-world applications, there is a pressing need for scalable platforms. On…
Collisional shift and broadening of Rydberg states in nitric oxide at room temperature
Fabian Munkes, Alexander Trachtmann, Patrick Kaspar +9
We report on the collisional shift and line broadening of Rydberg states in nitric oxide (NO) with increasing density of a background gas at room temperature. As a background gas w…
Observation of vibrational dynamics of orientated Rydberg-atom-ion molecules
Yi-Quan Zou, Moritz Berngruber, Viraatt S. V. Anasuri +4
Vibrational dynamics in conventional molecules usually takes place on a timescale of picoseconds or shorter. A striking exception are ultralong-range Rydberg molecules, for which d…
