Extreme-Scale Atomistic Simulation of Real-Temperature Magnetic Skyrmion Dynamics by Coupled Spin-Lattice Modeling
Pin Chen, Cheng-bing Chen, Hai Liu +9
Real-temperature topological magnetic dynamics in functional materials is governed by coupled lattice and spin evolution, yet remains inaccessible to predictive simulation at devic…
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…
Dirac Spin Liquid Candidate in a Rydberg Quantum Simulator
Guillaume Bornet, Marcus Bintz, Cheng Chen +10
We experimentally investigate a frustrated spin-exchange antiferromagnet in a quantum simulator, composed of N = 114 dipolar Rydberg atoms arranged into a kagome array. Motivated b…
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…
Transformer neural networks and quantum simulators: a hybrid approach for simulating strongly correlated systems
Hannah Lange, Guillaume Bornet, Gabriel Emperauger +5
Owing to their great expressivity and versatility, neural networks have gained attention for simulating large two-dimensional quantum many-body systems. However, their expressivity…
Enhancing a Many-body Dipolar Rydberg Tweezer Array with Arbitrary Local Controls
Guillaume Bornet, Gabriel Emperauger, Cheng Chen +8
We implement and characterize a protocol that enables arbitrary local controls in a dipolar atom array, where the degree of freedom is encoded in a pair of Rydberg states. Our appr…
Spectroscopy of elementary excitations from quench dynamics in a dipolar XY Rydberg simulator
Cheng Chen, Gabriel Emperauger, Guillaume Bornet +11
We use a Rydberg quantum simulator to demonstrate a new form of spectroscopy, called quench spectroscopy, which probes the low-energy excitations of a many-body system. We illustra…
