Signature of wave localisation in the time dependence of a reflected pulse
M. Titov, C. W. J. Beenakker
The average power spectrum of a pulse reflected by a disordered medium embedded in an N-mode waveguide decays in time with a power law t^(-p). We show that the exponent p increases…
Search for two-scale localization in disordered wires in a magnetic field
H. Schomerus, C. W. J. Beenakker
The supersymmetry technique [A. V. Kolesnikov and K. B. Efetov, Phys. Rev. Lett. 83, 3689 (1999)] predicts a two-scale behavior of wavefunction decay in disordered wires in the cro…
Phase-dependent magnetoconductance fluctuations in a chaotic Josephson junction
P. W. Brouwer, C. W. J. Beenakker
Motivated by recent experiments by Den Hartog et al., we present a random-matrix theory for the magnetoconductance fluctuations of a chaotic quantum dot which is coupled by point c…
Effect of the coupling to a superconductor on the level statistics of a metal grain in a magnetic field
K. M. Frahm, P. W. Brouwer, J. A. Melsen +1
A theory is presented for the statistics of the excitation spectrum of a disordered metal grain in contact with a superconductor. A magnetic field is applied to fully break time-re…
Non-perturbative calculation of the probability distribution of plane-wave transmission through a disordered waveguide
S. A. van Langen, P. W. Brouwer, C. W. J. Beenakker
A non-perturbative random-matrix theory is applied to the transmission of a monochromatic scalar wave through a disordered waveguide. The probability distributions of the transmitt…
Weak Localization Coexisting with a Magnetic Field in a Normal-Metal--Superconductor Microbridge
P. W. Brouwer, C. W. J. Beenakker
A random-matrix theory is presented which shows that breaking time-reversal symmetry by itself does {\em not} suppress the weak-localization correction to the conductance of a diso…
