Creating squeezed and non-classical collective motional many-body states through stroboscopic Rydberg dressing
Roman WuÃler, Chris Nill, Sylvain de Léséleuc +2
Realizing conditional quantum operations, e.g., quantum gates, for quantum computing and simulation requires controlled interactions between particles. Often, these interactions de…
The Boundary Time Crystal as a light source for collectively enhanced sensing
Malik Jirasek, Igor Lesanovsky, Albert Cabot
Modern precision measurements, such as interferometry for detecting gravitational waves, rely on the estimation of optical phases encoded in light fields. Here, we propose to explo…
Spectroscopic signatures of emergent elementary excitations in a kinetically constrained long-range interacting two-dimensional spin system
Tobias Kaltenmark, Chris Nill, Christian Groà +1
Lattice spin models featuring kinetic constraints constitute a paradigmatic setting for the investigation of glassiness and localization phenomena. The intricate dynamical behavior…
Collective cluster nucleation dynamics in quantum magnets
Philip Osterholz, Fabio Bensch, Shuanghong Tang +4
Strongly interacting many-body systems exhibit collective properties that emerge from complex correlations among microscopic degrees of freedom. These cooperative phenomena govern…
Entanglement of mechanical oscillators mediated by a Rydberg tweezer chain
Cedric Wind, Chris Nill, Julia Gamper +5
Mechanical systems provide a unique test bed for studying quantum phenomena at macroscopic length scales. However, realizing quantum states that feature quantum correlations among…
Magic running- and standing-wave optical traps for Rydberg atoms
Lukas Ahlheit, Chris Nill, Daniil Svirskiy +6
Magic trapping of ground and Rydberg states, which equalizes the AC Stark shifts of these two levels, enables increased ground-to-Rydberg state coherence times. We measure via phot…
