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…
Conductance of nanosystems with interaction
Anton Ramsak, Tomaz Rejec
The zero-temperature linear response conductance through an interacting mesoscopic region attached to noninteracting leads is investigated. We present a set of formulas expressing…
Spectral Functions and Pseudogap in Models of Strongly Correlated Electrons
P. Prelovsek, A. Ramsak
The theoretical investigation of spectral functions and pseudogap in systems with strongly correlated electrons is discussed, with the emphasis on the single-band t-J model as rele…
Spectral properties of underdoped cuprates
A. Ramsak, P. Prelovsek, I. Sega
In the framework of the planar t-J model for cuprates we analyze the development of a pseudo gap in the density of states, which at low doping starts to emerge for temperatures T<J…
Interacting electrons in a nearly straight quantum wire
T. Rejec, A. Ramsak, J. H. Jefferson
The conductance threshold of a clean nearly straight quantum wire in which a single electron is bound is studied. This exhibits spin-dependent conductance anomalies on the rising e…
Anomalies in the conduction edge of quantum wires
T. Rejec, A. Ramsak, J. H. Jefferson
We study the conductance threshold of clean nearly straight quantum wires in which an electron is bound. We show that such a system exhibits spin-dependent conductance structures o…
