One-dimensional density waves of ultracold bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate the propagation of density-wave packets in a Bose-Hubbard model using the adaptive time-dependent density-matrix renormalization group method. We discuss the decay o…
Charge oscillations in Quantum Dots: Renormalization group and Hartree method calculations
Michael Sindel, Alessandro Silva, Yuval Oreg +1
We analyze the local level occupation of a spinless, interacting two-level quantum dot coupled to two leads by means of Wilson's numerical renormalization group method. A gate volt…
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…
Frequency-dependent transport through a quantum dot in the Kondo regime
M. Sindel, W. Hofstetter, J. von Delft +1
We study the AC conductance and equilibrium current fluctuations of a Coulomb blockaded quantum dot. A relation between the equilibrium spectral function and the linear AC conducta…
