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…
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…
Tensor Network Python (TeNPy) version 1
Johannes Hauschild, Jakob Unfried, Sajant Anand +27
TeNPy (short for 'Tensor Network Python') is a python library for the simulation of strongly correlated quantum systems with tensor networks. The philosophy of this library is to a…
Supersolidity and Simplex Phases in Spin-1 Rydberg Atom Arrays
Vincent S. Liu, Marcus Bintz, Maxwell Block +3
Neutral atoms become strongly interacting when their electrons are excited to loosely bound Rydberg states. We investigate the strongly correlated quantum phases of matter that eme…
Intrinsic high-fidelity spin polarization of charged vacancies in hexagonal boron nitride
Wonjae Lee, Vincent S. Liu, Zhelun Zhang +11
The negatively charged boron vacancy () in hexagonal boron nitride (hBN) has garnered significant attention among defects in two-dimensional materials. T…
Dirac spin liquid in quantum dipole arrays
Marcus Bintz, Vincent S. Liu, Johannes Hauschild +4
We predict that the gapless Dirac spin liquid naturally emerges in a two-dimensional array of quantum dipoles. In particular, we demonstrate that the dipolar XY model$\unico…
