Strong Suppression of the Spin Hall Effect in the Spin Glass State
Y. Niimi, M. Kimata, Y. Omori +5
We have measured spin Hall effects in spin glass metals, CuMnBi alloys, with the spin absorption method in the lateral spin valve structure. Far above the spin glass temperature Tg…
Topologically-protected entanglement of electron pair cyclotron motions
T. Champel, D. Hernangómez-Pérez, S. Florens
Considering two-dimensional electron gases under a perpendicular magnetic field, we pinpoint a specific kind of long-range bipartite entanglement of the electronic motions. This en…
Thermoelectricity without absorbing energy from the heat sources
Robert. S. Whitney, Rafael Sánchez, Federica Haupt +1
We analyze the power output of a quantum dot machine coupled to two electronic reservoirs via thermoelectric contacts, and to two thermal reservoirs - one hot and one cold. This ma…
Effect of Photon-Assisted Andreev Reflection in the Accuracy of a SINIS Turnstile
Angelo Di Marco, Ville F. Maisi, Frank W. J. Hekking +1
We consider a hybrid single-electron transistor (SET) constituted by a gate-controlled normal-metal island (N) connected to two voltage-biased superconducting leads (S) by means of…
Detecting Photon-Photon Interactions in a Superconducting Circuit
Li-Jing Jin, Manuel Houzet, Julia S. Meyer +2
A local interaction between photons can be engineered by coupling a nonlinear system to a transmission line. The required high impedance transmission line can be conveniently forme…
Mode engineering with a one-dimensional superconducting metamaterial
Masahiko Taguchi, Denis M. Basko, Frank W. J. Hekking
We propose a way to control the Josephson energy of a single Josephson junction embedded in one- dimensional superconducting metamaterial: an inhomogeneous superconducting loop, ma…
