Quantum phase transitions in the systems of parallel quantum dots
Rok Zitko, Janez Bonca
We study the low-temperature transport properties of the systems of parallel quantum dots described by the N-impurity Anderson model. We calculate the quasiparticle scattering phas…
Thermal entanglement of qubit pairs on the Shastry-Sutherland lattice
S. El Shawish, A. Ramsak, J. Bonca
We show that temperature and magnetic field properties of the entanglement between spins on the two-dimensional Shastry-Sutherland lattice can be qualitatively described by analyti…
Kondo effect in triple quantum dots
R. Zitko, J. Bonca, A. Ramsak +1
Numerical analysis of the simplest odd-numbered system of coupled quantum dots reveals an interplay between magnetic ordering, charge fluctuations and the tendency of itinerant ele…
Enhanced Conductance Through Side-Coupled Double Quantum Dots
Rok Zitko, Janez Bonca
Conductance, on-site and inter-site charge fluctuations and spin correlations in the system of two side-coupled quantum dots are calculated using the Wilson's numerical renormaliza…
Comment on ''Kondo resonances and Fano antiresonances in transport through quantum dots''
J. Bonca, A. Ramsak, T. Rejec
We show that the numerical method [M.E. Torio, K. Hallberg, A.H. Ceccatto, and C.R. Proetto, Phys. Rev. B 65, 085302 (2002), cond-mat/0108167v2] does not reproduce correctly the Ko…
