Energy relaxation due to magnetic impurities in mesoscopic wires: Logarithmic approach
O. Ujsaghy, A. Jakovac, A. Zawadowski
The transport in mesoscopic wires with large applied bias voltage has recently attracted great interest by measuring the energy distribution of the electrons at a given point of th…
Role of surface anisotropy for magnetic impurities in electron dephasing and energy relaxation and their size effect
O. Ujsaghy, A. Jakovac, A. Zawadowski
Recently the electron dephasing and energy relaxation due to different magnetic impurities have been extensively investigated experimentally in thin wires and in this Letter these…
Can the Spin-Orbit Interaction Break the Channel Degeneracy of the Two-Channel Orbital Kondo Problem?
O. Ujsaghy, A. Zawadowski
Two-level systems (TLS) interacting with conduction electrons are possibly described by the two-channel Kondo Hamiltonian. In this case the channel degeneracy is due to the real sp…
The Role of Electron-Hole Symmetry Breaking in the Kondo Problems
O. Ujsaghy, K. Vladar, G. Zarand +1
In studying the different Kondo problems it is generally assumed that breaking the electron-hole symmetry does not affect the perturbative infrared divergencies. It is shown here t…
