Spin decoherence in graphene quantum dots due to hyperfine interaction
Moritz Fuchs, Valentin Rychkov, Björn Trauzettel
Carbon based systems are prominent candidates for a solid-state spin-qubit due to weak spin-orbit and hyperfine interactions in combination with a low natural abundance of spin car…
Multiscale approach to spin transport in magnetic multilayers
Simone Borlenghi, Valentin Rychkov, Cyril Petitjean +1
This article discusses two dual approaches to spin transport in magnetic multilayers: a direct, purely quantum, approach based on a Tight-Biding model (TB) and a semiclassical appr…
KNIT : An open source code for quantum transport in multi-terminal systems
Irina Rychkova, Valentin Rychkov, Kyryl Kazymyrenko +2
This paper is the documentation for a numerical code for quantum transport called KNIT. The KNIT library implements a generalization of the well known recursive Green function tech…
Spin torque and waviness in magnetic multilayers: a bridge between Valet-Fert theory and quantum approaches
Valentin S. Rychkov, Simone Borlenghi, Henri Jaffres +2
We develop a simple theoretical framework for transport in magnetic multilayers, based on Landauer-Buttiker scattering formalism and Random Matrix Theory. A simple transformation a…
Mesoscopic versus Macroscopic division of current fluctuations
Valentin S. Rychkov, Markus Buttiker
We investigate the current shot noise at a three terminal node in which one of the branches contains a noise generating source and the correlations are measured between the current…
Photon-assisted electron-hole shot noise in multi-terminal conductors
Valentin S. Rychkov, M. L. Polianski, M. Buttiker
Motivated by a recent experiment by L.-H. Reydellet et al., Phys. Rev. Lett. 90, 176803 (2003), we discuss an interpretation of photon-assisted shot noise in mesoscopic multiprobe…
