Finite temperature dynamical DMRG and the Drude weight of spin-1/2 chains
C. Karrasch, J. H. Bardarson, J. E. Moore
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…

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…
