1207.0295 (Maxim Drabkin et al.)

Transport in the random Kronig-Penney model    [PDF]

Maxim Drabkin, Werner Kirsch, Hermann Schulz-Baldes
The Kronig-Penney model with random Dirac potentials on the lattice $\ZM$ has critical energies at which the Lyapunov exponent vanishes and the density of states has a van Hove singularity. This leads to a non-trivial quantum diffusion even though the spectrum is known to be pure-point.
