Journal ArticleDOI
Observation of a discrete time crystal
Jiehang Zhang,Paul Hess,A. Kyprianidis,P. Becker,A. Lee,J. Smith,Guido Pagano,Ionut-Dragos Potirniche,Andrew C. Potter,Ashvin Vishwanath,Ashvin Vishwanath,Norman Y. Yao,Christopher Monroe +12 more
TL;DR: In this paper, the authors present the experimental observation of a discrete time crystal in an interacting spin chain of trapped atomic ions and apply a periodic Hamiltonian to the system under many-body localization conditions, and observe a subharmonic temporal response that is robust to external perturbations.
Journal ArticleDOI
Quantum oscillations from surface Fermi arcs in Weyl and Dirac semimetals
TL;DR: It is found that the open Fermi arcs participate in unusual closed magnetic orbits by traversing the bulk of the sample to connect opposite surfaces, and result in quantum oscillations that contain observable signatures of the topological character of the bulk Weyl semimetal.
Journal ArticleDOI
Discrete Time Crystals: Rigidity, Criticality, and Realizations
Norman Y. Yao,Andrew C. Potter,Andrew C. Potter,Ionut-Dragos Potirniche,Ashvin Vishwanath,Ashvin Vishwanath +5 more
TL;DR: A simple model for a one-dimensional discrete time crystal which explicitly reveals the rigidity of the emergent oscillations as the drive is varied is considered and a blueprint based upon a one dimensional chain of trapped ions is proposed.
Journal ArticleDOI
Landau quantization and quasiparticle interference in the three-dimensional Dirac semimetal Cd3As2
Sangjun Jeon,Brian B. Zhou,Andras Gyenis,Benjamin E. Feldman,Itamar Kimchi,Andrew C. Potter,Quinn Gibson,Robert J. Cava,Ashvin Vishwanath,Ali Yazdani +9 more
TL;DR: Scanning tunnelling microscopy measurements at sub-kelvin temperatures and high magnetic fields on the II-V semiconductor Cd3As2.2 show that defects mostly influence the valence band, consistent with the observation of ultrahigh-mobility carriers in the conduction band.
Journal ArticleDOI
Zero-bias peaks in the tunneling conductance of spin-orbit-coupled superconducting wires with and without Majorana end-states.
TL;DR: It is shown that this system generically exhibits a (nonquantized) zero-bias peak even when the wire is topologically trivial and does not possess Majorana end states, by simulating the tunneling conductance for multiband wires with realistic amounts of disorder.
