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…
Entanglement and charge-sharpening transitions in U(1) symmetric monitored quantum circuits
Utkarsh Agrawal, Aidan Zabalo, Kun Chen +5
Monitored quantum circuits can exhibit an entanglement transition as a function of the rate of measurements, stemming from the competition between scrambling unitary dynamics and d…
Quantum Hall network models as Floquet topological insulators
Andrew C. Potter, J. T. Chalker, Victor Gurarie
Network models for equilibrium integer quantum Hall (IQH) transitions are described by unitary scattering matrices, that can also be viewed as representing non-equilibrium Floquet…
Logarithmically Slow Relaxation in Quasi-Periodically Driven Random Spin Chains
Philipp T. Dumitrescu, Romain Vasseur, Andrew C. Potter
We simulate the dynamics of a disordered interacting spin chain subject to a quasi-periodic time-dependent drive, corresponding to a stroboscopic Fibonacci sequence of two distinct…
Localization-protected order in spin chains with non-Abelian discrete symmetries
Aaron J. Friedman, Romain Vasseur, Andrew C. Potter +1
We study the non-equilibrium phase structure of the three-state random quantum Potts model in one dimension. This spin chain is characterized by a non-Abelian symmetry recent…
Scaling Theory of Entanglement at the Many-Body Localization Transition
Philipp T. Dumitrescu, Romain Vasseur, Andrew C. Potter
We study the universal properties of eigenstate entanglement entropy across the transition between many-body localized (MBL) and thermal phases. We develop an improved real space r…
