Fermionic transport in a homogeneous Hubbard model: Out-of-equilibrium dynamics with ultracold atoms

Ulrich Schneider, Lucia Hackermüller, Jens Philipp Ronzheimer +8

Transport properties are among the defining characteristics of many important phases in condensed matter physics. In the presence of strong correlations they are difficult to predi…

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/…

Metallic and Insulating Phases of Repulsively Interacting Fermions in a 3D Optical Lattice

U. Schneider, L. Hackermuller, S. Will +6

The fermionic Hubbard model plays a fundamental role in the description of strongly correlated materials. Here we report on the realization of this Hamiltonian using a repulsively…

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…
