Kondo singlet from ferromagnetic coupling: an analog of Anderson-Morel superconductivity in the magnetic channel
Ewan Scott, Yaqi Chen, Michael Turaev +4
We consider magnetic impurities coupled to a conduction sea via a fully isotropic ferromagnetic spin-exchange term, the strength of which depends on the conduction-electron modes i…
Inverted anisotropy of the partially screened magnetic impurity
Krzysztof P. Wójcik, Michał P. Kwasigroch
We investigate a single magnetic impurity in the presence of strong spin-orbit coupling and single-ion anisotropy. We show that at sufficiently strong coupling there exists a finit…
Perfect spin polarization in T-shaped double quantum dots due to the spin-dependent Fano effect
K. P. Wojcik, I. Weymann
We study the spin-resolved transport properties of T-shaped double quantum dots coupled to ferromagnetic leads. Using the numerical renormalization group method, we calculate the l…
Proximity effect on spin-dependent conductance and thermopower of correlated quantum dots
Krzysztof P. Wojcik, Ireneusz Weymann
We study the electric and thermoelectric transport properties of correlated quantum dots coupled to two ferromagnetic leads and one superconducting electrode. Transport through suc…
Asymmetry-induced effects in Kondo quantum dots coupled to ferromagnetic leads
K. P. Wojcik, I. Weymann, J. Barnas
We study the spin-resolved transport through single-level quantum dots strongly coupled to ferromagnetic leads in the Kondo regime, with a focus on contact and material asymmetry-r…
A simple model of spontaneous emission
Krzysztof Piotr Wójcik
We present a very simple model of a spontaneous emission from a two-level atom, interacting with a field of a finite number of states. Such a process is often said to occur because…
