A renormalization group approach to time dependent transport through correlated quantum dots
D. M. Kennes, S. G. Jakobs, C. Karrasch +1
We introduce a real time version of the functional renormalization group which allows to study correlation effects on nonequilibrium transport through quantum dots. Our method is e…
Local spectral properties of Luttinger liquids: scaling versus nonuniversal energy scales
D. Schuricht, S. Andergassen, V. Meden
Motivated by recent scanning tunneling and photoemission spectroscopy measurements on self-organized gold chains on a germanium surface we reinvestigate the local single-particle s…
Supercurrent through a serial quantum dot close to singlet-triplet degeneracy
C. Karrasch, S. Andergassen, V. Meden
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…
Functional renormalization group approach to correlated fermion systems
Walter Metzner, Manfred Salmhofer, Carsten Honerkamp +2
Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon lowering the energy scale, collective phenomena, bound states, and new effective degrees of f…
