Using low-temperature scanning tunneling spectroscopy applied to the Cs-induced two-dimensional electron system (2DES) on p-type InSb(110), we probe electron-electron interaction effects in theâ€¦ (More)

We investigate the appearance of Ï€ lapses in the transmission phase Î¸ of a two-level quantum dot with Coulomb interaction U . Using the numerical and functional renormalization group methods we studyâ€¦ (More)

We propose an easily implemented approach to study time-dependent correlation functions of one-dimensional systems at finite-temperature T using the density matrix renormalization group. Theâ€¦ (More)

We investigate two serially aligned quantum dots in the molecular regime of large tunnel couplings t . A Zeeman field B is used to tune the energy difference of singlet and triplet spinâ€¦ (More)
