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…
Insensitivity to Time-Reversal Symmetry Breaking of Universal Conductance Fluctuations with Andreev Reflection
P. W. Brouwer, C. W. J. Beenakker
Numerical simulations of conduction through a disordered microbridge between a normal metal and a superconductor have revealed an anomalous insensitivity of the conductance fluctua…
Effect of a Voltage Probe on the Phase-Coherent Conductance of a Ballistic Chaotic Cavity
P. W. Brouwer, C. W. J. Beenakker
The effect of an invasive voltage probe on the phase-coherent conduction through a ballistic chaotic cavity is investigated by random-matrix theory. The entire distribution P(G) of…
