Large violation of Wiedemann Franz law in Luttinger liquids
Arti Garg, David Rasch, Efrat Shimshoni +1
We show that in weakly disordered Luttinger liquids close to a commensurate filling the ratio of thermal conductivity kappa and electrical conductivity sigma can deviate strongly f…
Large thermomagnetic effects in weakly disordered Heisenberg chains
E. Shimshoni, D. Rasch, P. Jung +2
The interplay of different scattering mechanisms can lead to novel effects in transport. We show theoretically that the interplay of weak impurity and Umklapp scattering in spin-1/…
Hybridisation in two-band Hubbard models with different bandwidths
Joerg Buenemann, David Rasch, Florian Gebhard
We investigate the orbital selective Mott transition in two-band Hubbard models by means of the Gutzwiller variational theory. In particular, we study the influence of a finite loc…
