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…
Maximized Orbital and Spin Kondo effects in a single-electron transistor
Karyn Le Hur, Pascal Simon, Laszlo Borda
We investigate the charge fluctuations of a single-electron box (metallic grain) coupled to a lead via a smaller quantum dot in the Kondo regime. The most interesting aspect of thi…
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…
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…
