Distribution of proper delay times in quantum chaotic scattering: a crossover from ideal to weak coupling.
نویسندگان
چکیده
The probability distribution of the proper delay times during scattering on a chaotic system is derived in the framework of the random matrix approach and the supersymmetry method. The result obtained is valid for an arbitrary number of scattering channels as well as arbitrary coupling to the energy continuum. The case of statistically equivalent channels is studied in detail. In particular, the semiclassical limit of an infinite number of weak channels is paid appreciable attention.

Magnetic scattering effects on magnetoresistance in a quasi-two-dimensional disordered electron system
Magnetic-impurity-scattering effects in a quasi-2D disordered electron system have been investigated theoretically with the diagrammatic techniques in perturbation theory. The analytical expressions for magnetoconductivities due to weak-localization effects have been obtained as functions of elastic, inelastic and magnetic scattering times. The relevant dimensional crossover behavior from 3D to...
متن کاملDistribution of the quantum mechanical time-delay matrix for a chaotic cavity
We calculate the joint probability distribution of the Wigner-Smith timedelay matrix Q = −ih̄ S−1∂S/∂ε and the scattering matrix S for scattering from a chaotic cavity with ideal point contacts. Hereto we prove a conjecture by Wigner about the unitary invariance property of the distribution functional P [S(ε)] of energy dependent scattering matrices S(ε). The distribution of the inverse of the e...

We describe electrical transport in ideal single-layer graphene at zero applied bias. There is a crossover from collisionless transport at frequencies larger than kBT/! (T is the temperature) to collision-dominated transport at lower frequencies. The d.c. conductivity is computed by the solution of a quantum Boltzmann equation. Due to a logarithmic singularity in the collinear scattering amplit...
متن کاملCalculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics
In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

– We investigate the distribution of the resonance widths P(Γ) and Wigner delay times P(τW) for scattering from two-dimensional systems in the diffusive regime. We obtain the forms of these distributions (log-normal for large τW and small Γ, and power law in the opposite case) for different symmetry classes and show that they are determined by the underlying diffusive classical dynamics. Our th...
