Ultrafast Dynamics of Vibrational Symmetry Breaking in a Charge-ordered Nickelate
Giacomo Coslovich, Alexander F. Kemper, Sascha Behl +6
The ability to probe symmetry breaking transitions on their natural time scales is one of the key challenges in nonequilibrium physics. Stripe ordering represents an intriguing typ…
Motion-induced signal revival in pulsed Rydberg four-wave mixing beyond the frozen gas limit
B. Huber, A. Kölle, T. Pfau
We present measurements on pulsed four-wave mixing involving a Rydberg state in an atomic vapor cell. The excitation to the Rydberg state is conducted by a pulsed two-photon excita…
Evidence for strong van der Waals-type Rydberg-Rydberg interaction in thermal vapor
T. Baluktsian, B. Huber, R. Löw +1
We present evidence for Rydberg-Rydberg interaction in a gas of rubidium atoms above room temperature. Rabi oscillations on the nanosecond timescale to different Rydberg states are…
Phase Fluctuations and the Absence of Topological Defects in Photo-excited Charge Ordered Nickelate
W. S. Lee, Y. D. Chuang, R. G. Moore +32
The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe sp…
GHz Rabi flopping to Rydberg states in hot atomic vapor cells
B. Huber, T. Baluktsian, M. Schlagmüller +4
We report on the observation of Rabi oscillations to a Rydberg state on a timescale below one nanosecond in thermal rubidium vapor. We use a bandwidth-limited pulsed excitation and…
