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…
Conductance Distribution of a Quantum Dot with Non-Ideal Single-Channel Leads
P. W. Brouwer, C. W. J. Beenakker
We have computed the probability distribution of the conductance of a ballistic and chaotic cavity which is connected to two electron reservoirs by leads with a single propagating…
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…
Doubled Shot Noise In Disordered Normal-Metal-Superconductor Junctions
M. J. M. de Jong, C. W. J. Beenakker
The low-frequency shot-noise power of a normal-metal-superconductor junction is studied for arbitrary normal region. Through a scattering approach, a formula is derived which expre…
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…
