Abstract

We theoretically investigate transport properties of a one-dimensional quantum wire (QW) connected with superconducting reservoirs, where the carriers in the QW are assumed to behave as a Tomonaga Luttinger liquid. With use of functional bosonization procedure, the system can be regarded as usual normal metal-superconductor junction in fluctuating 'environment' induced by electron-electron interactions. We show that this 'environment' suppresses the Andreev reflection processes at interfaces when the QW is adiabatically connected with the superconductors.
