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…
Conductance Fluctuations in a Disordered Double-Barrier Junction
J. A. Melsen, C. W. J. Beenakker
We consider the effect of disorder on coherent tunneling through two barriers in series, in the regime of overlapping transmission resonances. We present analytical calculations (u…
Scaling Theory of Conduction Through a Normal-Superconductor Microbridge
C. W. J. Beenakker, B. Rejaei, J. A. Melsen
The length dependence is computed of the resistance of a disordered normal-metal wire attached to a superconductor. The scaling of the transmission eigenvalue distribution with len…
Conductance Fluctuations, Weak Localization, and Shot Noise for a Ballistic Constriction in a Disordered Wire
C. W. J. Beenakker, J. A. Melsen
This is a study of phase-coherent conduction through a ballistic point contact with disordered leads. The disorder imposes mesoscopic (sample-to-sample) fluctuations and weak-local…
