Thermalization Universality-Class Transition Induced by Anderson Localization
Weihua Zhang, Gabriel M. Lando, Barbara Dietz +1
We study the disorder-induced crossover between the two recently discovered thermalization slowing-down universality classes -- characterized by long- and short-range coupling -- i…
Machine learning wave functions to identify fractal phases
Tilen Cadez, Barbara Dietz, Dario Rosa +3
We demonstrate that an image recognition algorithm based on a convolutional neural network provides a powerful procedure to differentiate between ergodic, non-ergodic extended (fra…
Time-reversal Invariance Violation and Quantum Chaos Induced by Magnetization in Ferrite-Loaded Resonators
Weihua Zhang, Xiaodong Zhang, Barbara Dietz
We investigate the fluctuation properties in the eigenfrequency spectra of flat cylindrical microwave cavities that are homogeneously filled with magnetized ferrite. These studies…
Experimental test of the Rosenzweig-Porter model for the transition from Poisson to Gaussian unitary ensemble statistics
Xiaodong Zhang, Weihua Zhang, Jiongning Che +1
We report on an experimental investigation of the transition of a quantum system with integrable classical dynamics to one with violated time-reversal (T) invariance and chaotic cl…
Properties of the eigenmodes and quantum-chaotic scattering in a superconducting microwave Dirac billiard with threefold rotational symmetry
Weihua Zhang, Xiaodong Zhang, Jiongning Che +2
We report on experimental studies that were performed with a microwave Dirac billiard (DB), that is, a flat resonator containing metallic cylinders arranged on a triangular grid, w…
