Weyl and Dirac semimetals in three-dimensional solids

NP Armitage, EJ Mele, A Vishwanath - Reviews of Modern Physics, 2018 - APS
Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Quantum computing with atomic qubits and Rydberg interactions: progress and challenges

Probing the quench dynamics of antiferromagnetic correlations in a 2D quantum Ising spin system

E Guardado-Sanchez, PT Brown, D Mitra, T Devakul… - Physical Review X, 2018 - APS
Simulating the real-time evolution of quantum spin systems far out of equilibrium poses a
major theoretical challenge, especially in more than one dimension. We experimentally …

Quench dynamics of a Fermi gas with strong nonlocal interactions

E Guardado-Sanchez, BM Spar, P Schauss… - Physical Review X, 2021 - APS
We induce strong nonlocal interactions in a 2D Fermi gas in an optical lattice using Rydberg
dressing. The system is approximately described by at-V model on a square lattice where …

Weyl semimetal to metal phase transitions driven by quasiperiodic potentials

JH Pixley, JH Wilson, DA Huse, S Gopalakrishnan - Physical review letters, 2018 - APS

Topological quantum liquids with long-range couplings

K Patrick, T Neupert, JK Pachos - Physical review letters, 2017 - APS
Very few topological systems with long-range couplings have been considered so far due to
our lack of analytic approaches. Here we extend the Kitaev chain, a 1D quantum liquid, to …

Symmetry-protected topological phases in a Rydberg glass
