Reply to Comment on "Discrete Time Crystals: Rigidity Criticality and Realizations"
Norman Y. Yao, Andrew C. Potter, Ionut-Dragos Potirniche +1
This is a reply to the comment from Khemani, Moessner and Sondhi (KMS) [arXiv:2109.00551] on our manuscript [Phys. Rev. Lett. 118, 030401 (2017)]. The main new claim in KMS is that…
Integrable and chaotic dynamics of spins coupled to an optical cavity
Gregory Bentsen, Ionut-Dragos Potirniche, Vir B. Bulchandani +5
We show that a class of random all-to-all spin models, realizable in systems of atoms coupled to an optical cavity, gives rise to a rich dynamical phase diagram due to the pairwise…
On the stability of many-body localization in
Ionut-Dragos Potirniche, Sumilan Banerjee, Ehud Altman
Recent work by De Roeck et al. [Phys. Rev. B 95, 155129 (2017)] has argued that many-body localization (MBL) is unstable in two and higher dimensions due to a thermalization avalan…
Floquet symmetry-protected topological phases in cold atomic systems
Ionut-Dragos Potirniche, Andrew C. Potter, Monika Schleier-Smith +2
We propose and analyze two distinct routes toward realizing interacting symmetry-protected topological (SPT) phases via periodic driving. First, we demonstrate that a driven transv…
Observation of a Discrete Time Crystal
J. Zhang, P. W. Hess, A. Kyprianidis +9
Spontaneous symmetry breaking is a fundamental concept in many areas of physics, ranging from cosmology and particle physics to condensed matter. A prime example is the breaking of…
Discrete time crystals: rigidity, criticality, and realizations
Norman Y. Yao, Andrew C. Potter, Ionut-Dragos Potirniche +1
Despite being forbidden in equilibrium, spontaneous breaking of time translation symmetry can occur in periodically driven, Floquet systems with discrete time-translation symmetry.…
Classical-Quantum Mixing in the Random 2-Satisfiability Problem
Ionut-Dragos Potirniche, C. R. Laumann, S. L. Sondhi
Classical satisfiability (SAT) and quantum satisfiability (QSAT) are complete problems for the complexity classes NP and QMA which are believed to be intractable for classical and…
Superconductivity of disordered Dirac fermions in graphene
Ionut-Dragos Potirniche, Joseph Maciejko, Rahul Nandkishore +1
We numerically study the interplay between superconductivity and disorder on the graphene honeycomb lattice with on-site Hubbard attractive interactions U using a spatially inhomog…
