Dissipation-induced quantum phase transition in a quantum box
L. Borda, G. Zarand, P. Simon
In a recent work, Le Hur has shown that dissipative coupling to gate electrodes may play an important role in a quantum box near its degeneracy point [K. Le Hur, Phys. Rev. Lett. {…
Gate-controlled spin-splitting in quantum dots with ferromagnetic leads in the Kondo regime
J. Martinek, M. Sindel, L. Borda +6
The effect of a gate voltage () on the spin-splitting of an electronic level in a quantum dot (QD) attached to ferromagnetic leads is studied in the Kondo regime using a gener…
Assisted hopping and interaction effects in impurity models
L. Borda, F. Guinea
We study, using Numerical Renormalization Group methods, the generalization of the Anderson impurity model where the hopping depends on the filling of the impurity. We show that th…
Regular and Singular Fermi Liquid fixed points in quantum impurity models
Pankaj Mehta, L. Borda, Gergely Zarand +2
We show that thermodynamics is insufficient to probe the nature of the low energy dynamics of quantum impurity models and a more subtle analysis based on scattering theory is requi…
Theory of inelastic scattering from magnetic impurities
G. Zarand, L. Borda, Jan von Delft +1
We use the numerical renormalization group method tocalculate the single particle matrix elements of the many body -matrix of the conduction electrons scattered by a ma…
