Realizing Rydberg induced long-range interactions in itinerant lattice systems

• Applicant: Professor Dr. Immanuel Bloch
• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: from 2019 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 428456515

The project aims at realizing intinerant lattice systems using Rydberg atoms in optical lattices. Based on new approaches on "Rydberg dressing", it aims at realizing mobile lattice gases beyond the frozen gas regime, which exhibit long range interactions. The emergent new many-body quantum phases and their dynamics will be studied in the experiment. The project is based on exciting new results in the first project phase on Rydberg macrodimers that opened up new pathways for improved dressing schemes to realize such systems.In order to analyze these long-range interacting systems, quantum gas microscopes will be used that allow for an efficient single atom detection with single lattice site resolution. This enables to directly reveal complex spin and density correlations in the systems. The project thereby promises to yield fundamentally new insights into the molcular and many-body physics of long-range interacting Rydberg systems.
