Spin order in the one-dimensional Kondo and Hund lattices
D. J. Garcia, K. Hallberg, B. Alascio +1
We study numerically the one-dimensional Kondo and Hund lattices consisting of localized spins interacting antiferro or ferromagnetically with the itinerant electrons, respectively…
Detection of topological transitions by transport through molecules and nanodevices
A. A. Aligia, K. Hallberg, B. Normand +1
We analyze the phase transitions of an interacting electronic system weakly coupled to free-electron leads by considering its zero-bias conductance. This is expressed in terms of t…
Charge and spin conductance through a side-coupled quantum dot
M. E. Torio, K. Hallberg, C. Proetto
The zero-temperature magnetic field-dependent conductance of electrons through a one-dimensional non-interacting tight-binding chain with an interacting {\it side} dot is reviewed…
Dynamical Mean Field Theory with the Density Matrix Renormalization Group
Daniel J. Garcia, Karen Hallberg, Marcelo J. Rozenberg
A new numerical method for the solution of the Dynamical Mean Field Theory's self-consistent equations is introduced. The method uses the Density Matrix Renormalization Group techn…
Spin filters with Fano dots
M. E. Torio, K. Hallberg, S. Flach +2
We compute the zero bias conductance of electrons through a single ballistic channel weakly coupled to a side quantum dot with Coulomb interaction. In contrast to the standard setu…
