International audience; We study a single-level quantum dot in the presence of strong Coulomb interaction under nonequilibrium condition. By extending the equation of motion method to nonequilibrium, we study the transport behavior of the system when

We consider a magnetic impurity deposited on the surface of a strong topological insulator and interacting with the surface modes by a Kondo exchange interaction. Taking into account the warping of the Fermi line of the surface modes, we derive a map

Lifshitz transition in Kondo alloys

Autor: Claudine Lacroix, Sébastien Burdin

Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2013, 110 (22), pp.226403. ⟨10.1103/PhysRevLett.110.226403⟩

We study the low energy states of Kondo alloys as function of the magnetic impurity concentration per site, x, and the conduction electron average site occupation, nc. Using two complementary approaches, the mean-field coherent potential approximatio

We study the Josephson effect through a magnetic molecule with anisotropic properties. Performing calculations in the tunneling regime, we show that the exchange coupling between the electron spin on the molecule and the molecular spin can trigger a

Theory of the non-Fermi-liquid transition point in the two-impurity Kondo model

Autor: Clément Sire, Chandra Varma, H. R. Krishnamurthy

We present an explicit solution of the problem of two coupled spin-1/2 impurities, interacting with a band of conduction electrons. We obtain an exact effective bosonized Hamiltonian, which is then treated by two different methods (low-energy theory
