Quantum phase transition in a two-channel-Kondo quantum dot device
M. Pustilnik, L. Borda, L. I. Glazman +1
We develop a theory of electron transport in a double quantum dot device recently proposed for the observation of the two-channel Kondo effect. Our theory provides a strategy for t…
NRG study of the Kondo effect in the presence of itinerant-electron ferromagnetism
J. Martinek, M. Sindel, L. Borda +4
The Kondo effect in quantum dots (QDs) - artificial magnetic impurities - attached to ferromagnetic leads is studied with the numerical renormalization group (NRG) method. It is sh…
Quantum Magnetic Impurities in Magnetically Ordered Systems
A. H. Castro Neto, E. Novais, L. Borda +2
We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level…
Orbital Kondo behavior from dynamical structural defects
L. Borda, A. Zawadowski, G. Zarand
The interaction between an atom moving in a model double-well potential and the conduction electrons is treated using renormalization group methods in next-to-leading logarithmic o…
