Local density of states in a dirty normal metal connected to a superconductor.
A superconductor in contact with a normal metal not only induces superconducting correlations, known as the proximity effect, but also modifies the density of states at some distance from the interface. These modifications can be resolved experimentally in microstructured systems. We therefore study the local density of states N(E ,x) of a superconductor–normal-metal heterostructure. We find a ...
متن کاملSize effects in the density of states in normal-metal-superconductor and superconductor-normal-metal-superconductor junctions.
The quasiparticle local density of states ~LDOS! is studied in clean normal-metal–superconductor ~NS! and superconductor–normal-metal–superconductor ~SNS! junctions with increasing transverse size, from quasione-dimensional to three-dimensional. It is shown that finite transverse dimensions are related to pronounced effects in the LDOS, such as fast oscillations superimposed on the quasiparticl...

متن کاملLocal Density of States in Superconductor - Ferromagnetic Hybrid Systems
In this Letter we discuss various properties of the local density of states (DOS) for a superconductor-ferromagnet hybrid system. The DOS is modified at small energies on both sides of the interface. Due to the interplay of superconductivity and ferromagnetism, the local DOS depends on the spin direction. The spin polarization effects extend over a long distance from the interface both in the s...
متن کاملPhase states of multiterminal mesoscopic normal-metal-superconductor structures.
We study a mesoscopic normal-metal structure with four superconducting contacts, two of which are joined into a loop. The structure undergoes transitions between three (meta)stable states, with different phase configurations triggered by nonequilibrium conditions. These transitions result in spectacular changes in the magnetoresistance. We find a qualitative agreement between the experiments an...
