Flux-tunable barrier in proximity Josephson junctions
Jian Wei, P. Cadden-Zimansky, P. Virtanen +1
We report experiments on micron-scale normal metal loop connected by superconducting wires, where the sample geometry enables full modulation of the thermal activation barrier with…
Peltier effects in Andreev interferometers
Pauli Virtanen, Tero T. Heikkila
The superconducting proximity effect is known to modify transport properties of hybrid normal--superconducting structures. In addition to changing electrical and thermal transport…
Nonequilibrium characteristics in all-superconducting tunnel structures
M. A. Laakso, P. Virtanen, F. Giazotto +1
We study the nonequilibrium characteristics of superconducting tunnel structures in the case when one of the superconductors is a small island confined between large superconductor…
Influence of Supercurrents on Low-Temperature Thermopower in Mesoscopic N/S Structures
J. Zou, I. Sosnin, P. Virtanen +3
The thermopower of mesoscopic normal metal/superconductor structures has been measured at low temperatures. Effect of supercurrent present in normal part of the structure was studi…
Supercurrent-induced temperature gradient across a nonequilibrium SNS Josephson junction
M. S. Crosser, Pauli Virtanen, Tero T. Heikkilä +1
Using tunneling spectroscopy, we have measured the local electron energy distribution function in the normal part of a superconductor-normal metal-superconductor (SNS) Josephson ju…
Circuit theory for noise in incoherent normal-superconducting dot structures
P. Virtanen, T. T. Heikkila
We consider the current fluctuations in a mesoscopic circuit consisting of nodes connected by arbitrary connectors, in a setup with multiple normal or superconducting terminals. In…
