Observing weakly broken conservation laws in a dipolar Rydberg quantum spin chain

Cheng Chen, Luca Capizzi, Alice Marché +6

Integrable quantum many-body systems host families of extensive conservation laws, some of which are fragile: even infinitesimal perturbations can qualitatively alter their dynamic…

Probing spin-motion coupling of two Rydberg atoms by a Stern-Gerlach-like experiment

Gabriel Emperauger, Mu Qiao, Guillaume Bornet +7

We propose and implement a protocol to measure the state-dependent motion of Rydberg atoms induced by dipole-dipole interactions. Our setup enables simultaneous readout of both the…

Benchmarking direct and indirect dipolar spin-exchange interactions between two Rydberg atoms

Gabriel Emperauger, Mu Qiao, Guillaume Bornet +8

We report on the experimental characterization of various types of spin-exchange interactions between two individual atoms, where pseudo-spin degrees of freedom are encoded in diff…

Tomonaga-Luttinger Liquid Behavior in a Rydberg-encoded Spin Chain

Gabriel Emperauger, Mu Qiao, Cheng Chen +14

Quantum fluctuations can disrupt long-range order in one-dimensional systems, and replace it with the universal paradigm of the Tomonaga-Luttinger liquid (TLL), a critical phase of…

Realization of a doped quantum antiferromagnet with dipolar tunnelings in a Rydberg tweezer array

Mu Qiao, Gabriel Emperauger, Cheng Chen +13

Doping an antiferromagnetic Mott insulator is central to our understanding of a variety of phenomena in strongly-correlated electrons, including high-temperature superconductors. T…
