Shot Noise and Proximity Effect in Superconductor–normal-metal Heterostructures
Current noise provides useful information on correlations important for transport properties of mesoscopic systems. Of particular interest, both experimentally and theoretically, are heterostructures of normal metals and superconductors. We use an extended Keldysh-Green’s function approach to calculate the current correlations fully accounting for the superconducting proximity effect. The shot ...
متن کاملOdd-frequency pairing in superconducting heterostructures.
We review the theory of odd-frequency pairing in superconducting heterostructures, where an odd-frequency pairing component is induced near interfaces. A general description of the superconducting proximity effect in a normal metal or a ferromagnet attached to an unconventional superconductor (S) is given within quasiclassical kinetic theory for various types of symmetry state in S. Various pos...
متن کاملCurrent induced decomposition of Abrikosov vortices in p-n layered superconductors and heterostructures.
We describe the decomposition of Abrikosov vortices into decoupled pancake vortices in superconductors having both electron and hole charge carriers. We estimate the critical current of such a decomposition, at which a superconducting-normal state transition occurs, and find that it is very sensitive to the magnetic field and temperature. The effect can be observed in recently synthesized self-...
متن کاملFull counting statistics of incoherent Andreev transport
– We study the full counting statistics of heterostructures consisting of normalmetal parts connected to a superconducting terminal. Assuming that coherent superconducting correlations are suppressed in the normal metals, we show, using the Keldysh-Nambu Green’s function approach, that the system can be mapped onto a purely normal system with twice the number of elements. For a superconducting ...
