Pw. Brouwer et Cwj. Beenakker, DIAGRAMMATIC METHOD OF INTEGRATION OVER THE UNITARY-GROUP, WITH APPLICATIONS TO QUANTUM TRANSPORT IN MESOSCOPIC SYSTEMS, Journal of mathematical physics, 37(10), 1996, pp. 4904-4934
A diagrammatic method is presented for averaging over the circular ens
emble of random-matrix theory. The method is applied to phase-coherent
conduction through a chaotic cavity (a ''quantum dot'') and through t
he interface between a normal metal and a superconductor. (C) 1996 Ame
