Linear AC Response of Diffusive SNS Junctions
Pauli Virtanen, F. Sebastián Bergeret, Juan Carlos Cuevas +1
We explore the behavior of the ac admittance of superconductor-normal metal-superconductor (SNS) junctions as the phase difference of the order parameters between the superconducto…
Spatially-resolved probing of a non-equilibrium superconductor
K. Yu. Arutyunov, H. -P. Auraneva, A. S. Vasenko
Spatially resolved relaxation of non-equilibrium quasiparticles in a superconductor at ultra-low temperatures was experimentally studied. It was found that the quasiparticle inject…
Surface defects and conduction in polar oxide heterostructures
N. C. Bristowe, P. B. Littlewood, Emilio Artacho
The polar interface between LaAlO and SrTiO has shown promise as a field effect transistor, with reduced (nanoscale) feature sizes and potentially added functionality o…
Theory of microwave-assisted supercurrent in quantum point contacts
F. S. Bergeret, P. Virtanen, T. T. Heikkilä +1
We present a microscopic theory of the effect of a microwave field on the supercurrent through a quantum point contact of arbitrary transmission. Our theory predicts that: (i) for…
A Composite Fermion Approach to the Ultracold Dilute Fermi Gas
M. A. Cazalilla
It is argued that the recently observed Fermi liquids in strongly interacting ultracold Fermi gases are adiabatically connected to a projected Fermi gas. This conclusion is reached…
Potential Energy Landscape for hot electrons in periodically nanostructured graphene
B. Borca, S. Barja, M. Garnica +9
We explore the spatial variations of the unoccupied electronic states of graphene epitaxially grown on Ru(0001) and observed three unexpected features: the first graphene image sta…
