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/…
Spin conductivity in almost integrable spin chains
Peter Jung, Achim Rosch
The spin conductivity in the integrable spin-1/2 XXZ-chain is known to be infinite at finite temperatures T for anisotropies -1 < Delta < 1. Perturbations which break integrability…
Lower bounds for the conductivities of correlated quantum systems
Peter Jung, Achim Rosch
We show how one can obtain a lower bound for the electrical, spin or heat conductivity of correlated quantum systems described by Hamiltonians of the form H = H0 + g H1. Here H0 is…
Transport in Almost Integrable Models: Perturbed Heisenberg Chains
P. Jung, R. W. Helmes, A. Rosch
The heat conductivity kappa(T) of integrable models, like the one-dimensional spin-1/2 nearest-neighbor Heisenberg model, is infinite even at finite temperatures as a consequence o…
