Coherent transport and dynamical entropy for Fermionic systems

摘要

This paper consists in two parts. First we set up a general scheme of localtraps in an homogeneous deterministic quantum system. The current of particlescaught by the trap is linked to the dynamical behaviour of the trap states. Inthis way, transport properties in an homogeneous system are related to spectralproperties of a coherent dynamics. Next we apply the scheme to a system ofFermions in the one-particle approximation. We obtain in particular lowerbounds for the dynamical entropy in terms of the current induced by the trap.
