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/…
Metastable superfluidity of repulsive fermionic atoms in optical lattices
Achim Rosch, David Rasch, Benedikt Binz +1
In the fermionic Hubbard model, doubly occupied states have an exponentially large lifetime for strong repulsive interactions U. We show that this property can be used to prepare a…
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…
