Abstract We study the breaking of time-reversal invariance (TRI) by the application of a magnetic field in the quantum kicked rotor (QKR), using Izrailev’s finite-dimensional model. There is a continuous crossover from TRI to time-reversal non-invariance (TRNI) in the spectral and eigenvector fluctuations of the QKR. We show that the properties of this TRI…

Statistics of energy levels without time-reversal symmetry: Aharonov-Bohm chaotic billiards

A planar domain D contains a single line of magnetic flux Phi . Switching on Phi breaks time-reversal symmetry (T) for quantal particles with charge q moving in D, whilst preserving the geometry of

Eigenvalue correlations in the circular ensembles

Dyson (1972) introduced two types of Brownian-motion ensembles of random matrices for studying approximate symmetries in complex quantum systems. The magnitude of symmetry breaking plays the role of

Crossover from Orthogonal to Unitary Symmetry for Ballistic Electron Transport in Chaotic Microstructures

Abstract We study the ensemble-averaged conductance as a function of applied magnetic field for ballistic electron transport across few-channel microstructures constructed in the shape of classically

The effect of symmetry-breaking in `chaotic' spectral correlations

We show, using semiclassical methods, that the spectral correlations of quantum maps undergo a rapid transition from one universality class to another when the symmetry of the system is gradually

Brownian-Motion Model of Quantum-Chaotic Spectra: Exact Two-level Correlations for Transitions to CUE

Spectral fluctuations in quantum-chaotic systems undergo transition from one universality class to another as a good symmetry of the system is gradually broken. After suitable rescaling and limits,

Chaotic dynamics and the GOE-GUE transition

The statistical fluctuations of the energy levels of classically chaotic systems are believed to coincide with those of Gaussian matrix ensembles. The transition from the Gaussian orthogonal ensemble

Quantum signatures of chaos

The distinction between level clustering and level repulsion is one of the quantum analogues of the classical distinction between globally regular and predominantly chaotic motion (see Figs. 1, 2,
