Normal-transport behavior in finite one-dimensional chaotic quantum systems

  title={Normal-transport behavior in finite one-dimensional chaotic quantum systems},
  author={Robin Steinigeweg and Jochen Gemmer and Mathias Michel},
We investigate the transport of energy, magnetization, etc. in several finite one-dimensional (1D) quantum systems only by solving the corresponding time-dependent Schrodinger equation. We explicitly renounce any other transport analysis technique. Varying model parameters we find a sharp transition from non-normal to normal transport and a transition from integrability to chaos, i.e., from Poissonian to Wigner-like level statistics. These transitions always appear in conjunction with each…

We study transport of local magnetization in a Heisenberg spin-1/2 chain at zero temperature. The system is initially prepared in a highly excited pure state far from equilibrium and its evolution is

Domain wall dynamics in integrable and chaotic spin-1/2 chains.
A monotonic correspondence between the enhancement of the level of delocalization, spin current, and magnetization dynamics occurs in the integrable domain, but this correspondence is lost for chaotic models with weak Ising interactions.
