String order parameters for 1d Floquet Symmetry Protected Topological Phases
Ajesh Kumar, Philipp T. Dumitrescu, Andrew C. Potter
Floquet symmetry protected topological (FSPT) phases are non-equilibrium topological phases enabled by time-periodic driving. FSPT phases of 1d chains of bosons, spins, or qubits h…
Thermodynamic signatures for the existence of Dirac electrons in ZrTe5
Nityan L. Nair, Philipp T. Dumitrescu, Sanyum Channa +4
We combine transport, magnetization, and torque magnetometry measurements to investigate the electronic structure of ZrTe5 and its evolution with temperature. At fields beyond the…
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…
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…
