Scaling theory of conduction through a normal-superconductor microbridge.
نویسندگان
چکیده
The length dependence is computed of the resistance of a disordered normalmetal wire attached to a superconductor. The scaling of the transmission eigenvalue distribution with length is obtained exactly in the metallic limit, by a transformation onto the isobaric flow of a two-dimensional ideal fluid. The resistance has a minimum for lengths near l/Γ, with l the mean free path and Γ the transmittance of the superconductor interface.

Insensitivity to time-reversal symmetry breaking of universal conductance fluctuations with Andreev reflection.
Numerical simulations of conduction through a disordered microbridge between a normal metal and a superconductor have revealed an anomalous insensitivity of the conductance fluctuations to a magnetic field. A theory for the anomaly is presented: Both an exact analytical calculation (using randommatrix theory) and a qualitative symmetry argument (involving the exchange of time-reversal for refle...
متن کاملWeak localization coexisting with a magnetic field in a normal-metal-superconductor microbridge.
A random-matrix theory is presented which shows that breaking time-reversal symmetry by itself does not suppress the weak-localization correction to the conductance of a disordered metal wire attached to a superconductor. Suppression of weak localization requires applying a magnetic field as well as raising the voltage, to break both time-reversal symmetry and electron-hole degeneracy. A magnet...
متن کاملQuantum transport in semiconductor-superconductor microjunctions.
Recent experiments on conduction between a semiconductor and a superconductor have revealed a variety of new mesoscopic phenomena. Here is a review of the present status of this rapidly developing field. A scattering theory is described which leads to a conductance formula analogous to Landauer’s formula in normal-state conduction. The theory is used to identify features in the conductance whic...
متن کاملDiagrammatic method of integration over the unitary group, with applications to quantum transport in mesoscopic systems
A diagrammatic method is presented for averaging over the circular ensemble of random-matrix theory. The method is applied to phase-coherent conduction through a chaotic cavity (a “quantum dot”) and through the interface between a normal metal and a superconductor.
متن کاملTheory of quantum metal to superconductor transitions in highly conducting systems
We derive the theory of the quantum (zero temperature) superconductor to metal transition in disordered materials when the resistance of the normal metal near criticality is small compared to the quantum of resistivity. This can occur most readily in situations in which “Anderson’s theorem” does not apply. We explicitly study the transition in superconductor-metal composites, in an swave superc...
