Absorption and Emission in quantum dots: Fermi surface effects of Anderson excitons
R. W. Helmes, M. Sindel, L. Borda +1
Recent experiments measuring the emission of exciton recombination in a self-organized single quantum dot (QD) have revealed that novel effects occur when the wetting layer surroun…
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…
Spatial correlations of trapped 1d bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate a quasi-one dimensional system of trapped cold bosonic atoms in an optical lattice by using the density matrix renormalization group to study the Bose-Hubbard model…
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…
Dissipative spin-boson model and Kondo effect in low dimensional quantum gases
A. Recati, P. O. Fedichev, W. Zwerger +2
We show that ultracold atoms confined in a quasi-1d trap can be used to study the dissipative spin-boson model with {\it tunable} tunneling splitting and strength of dissipation. I…
