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…
A Dipolar Chiral Spin Liquid on the Breathed Kagome Lattice
Francisco Machado, Sabrina Chern, Michael P. Zaletel +1
Continuous control over lattice geometry, when combined with long-range interactions, offers a powerful yet underexplored tool to generate highly frustrated quantum spin systems. B…
Ground states of quantum XY dipoles on the Archimedean lattices
Marcus Bintz, Ahmed Khalifa, Vincent S. Liu +4
We report numerical ground states for the dipolar XY spin model, which describes extended antiferromagnetic interactions in two-dimensional arrays of polar molecules and two-level…
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…
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…
