2. 1. Simulations of thermoelectric transport in granularsuperconductors

   Author : Andreas Andersson; Jack Lidmar; Vladimir Krasnov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Supraledning;

   Abstract : This thesis presents results from numerical simulations of the Nernst effect dueto phase fluctuations in models of two-dimensional granular superconductors. Inaddition other transport properties, such as thermal conductivity and electrical re-sistivity are calculated. READ MORE
