Anomalous Quantum Diffusion and Conductivity of Quasicrystals
Didier Mayou
A phenomenological diffusion law , where L(t) measures the spreading of a wave-packet in a time t, is assumed for perfect quasicrystals. We show that it affects th…

Conditions on the Occurrence of Magnetic Moments in Quasicrystals and Related Phases
Guy Trambly de Laissardiere, Didier Mayou
We analyze the criterion for the appearance of magnetic moments in quasicrystals approximants and liquids Al-Mn. In a Hartree-Fock scheme, it is shown that the Stoner criterion (Un…

Conductivity in 3D quasiperiodic systems
S. Roche, D. Mayou
We develop a new real-space method which allows to evaluate the Kubo-Greenwood conductivity of independent electrons in static aperiodic potentials. We apply it to a numerical stud…
