Weak links in proximity superconducting two dimensional electron systems
N. B. Kopnin, A. S. Mel'nikov, I. A. Sadovskyy +1
We report a giant inverse proximity effect that arises in the low-dimensional devices and is crucially different from proximity in the standard superconductor-normal-superconductor…
Information flow and optimal protocol for Maxwell's demon single electron pump
J. Bergli, Y. M. Galperin, N. B. Kopnin
We study the entropy and information flow in a Maxwell demon device based on a single-electron transistor with controlled gate potentials. We construct the protocols for measuring…
Vortex matter in low dimensional systems with proximity induced superconductivity
N. B. Kopnin, I. M. Khaymovich, A. S. Mel'nikov
We study theoretically the vortex matter structure in low dimensional (LD) systems with superconducting order induced by proximity to a bulk superconductor. We analyze the effects…
Surface superconductivity in rhombohedral graphite
N. B. Kopnin, T. T. Heikkila
We show that rhombohedral graphite may support surface superconductivity with an unusual relation between the BCS coupling constant and the order parameter. This feature results fr…
High-temperature surface superconductivity in rhombohedral graphite
N. B. Kopnin, M. Ijäs, A. Harju +1
Surface superconductivity in rhombohedral graphite is a robust phenomenon which can exist even when higher order hoppings between the layers lift the topological protection of the…
Multiple Vortex Cores in 2D Electronic Systems with Proximity Induced Superconductivity
N. B. Kopnin, I. M. Khaymovich, A. S. Mel'nikov
The structure of a proximity induced vortex core in a two-dimensional (2D) metallic layer covering a superconducting half-space is calculated. We predict formation of a multiple vo…
