Universality Emerging in a Universality: Derivation of the Ericson Transition in Stochastic Quantum Scattering and Experimental Validation
Simon Köhnes, Jiongning Che, Barbara Dietz +1
At lower energies, the resonances in scattering experiments are often isolated. In quantum chaotic many-body, disordered or generically stochastic systems, the resonances overlap a…
Experimental study of coupled quantum billiards with integrable and chaotic classical dynamics and test of a special Rosenzweig-Porter model
Xiaodong Zhang, Jiongning Che, Barbara Dietz
We report on the experimental study of the spectral properties of quantum systems consisting of two quantum billiards (QBs), one with chaotic, the other one with integrable classic…
Experimental study of the distributions of off-diagonal scattering-matrix elements of quantum graphs with symplectic symmetry
Jiongning Che, Nils Gluth, Simon Köhnes +2
We report on experimental studies of the distribution of the off-diagonal elements of the scattering matrix of open microwave networks with symplectic symmetry and a chaotic wave d…
Exact Results for the Ericson Transition in Stochastic Quantum Scattering and Experimental Validation
Simon Köhnes, Jiongning Che, Barbara Dietz +1
At lower energies, the resonances in scattering experiments are often isolated. The crucial parameter is the ratio of average resonance width and average mean level spacing. Toward…
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…
Experimental study of closed and open microwave waveguide graphs with preserved and partially violated time-reversal invariance
Weihua Zhang, Xiaodong Zhang, Jiongning Che +3
We report on experiments that were performed with microwave waveguide systems and demonstrate that in the frequency range of a single transversal mode they may serve as a model for…
Missing-level statistics in classically chaotic quantum systems with symplectic symmetry
Jiongning Che, Junjie Lu, 2 Xiaodong Zhang +2
We present experimental and theoretical results for the fluctuation properties in the incomplete spectra of quantum systems with symplectic symmetry and a chaotic dynamics in the c…
Universal S-matrix correlations for complex scattering of many-body wavepackets: theory, simulation and experiment
Andreas Bereczuk, Barbara Dietz, Jiongning Che +3
We present an in-depth study of the universal correlations of scattering-matrix entries required in the framework of non-stationary many-body scattering where the incoming states a…
