Mathematical Theory of Aperiodic Solids:

• Structure: the Hull, transversal, equilibrium Gibbs state, diffraction measure.
• Application to: Bloch electrons in magnetic field, quasycrystals, semiconductors at low temperature.
• Noncommutative Geometry: the noncommutative Brillouin zone, electrons & phonons.
• Topological invariants:K-theory and Gap Labeling theorem
• Electronic and spectral properties of aperiodic media: Cantor and Singular spectra for electron or phonons. Anderson localization, weak localization and Random Matrix Theory.
• Coherent transport: spectral and transport exponents
• Dissipative transport: the Greene-Kubo formulae, models for dissipation, Mott's variable range hopping.
• Noncommutative Geometry: cyclic cohomology, application to the theory of the Quantum Hall effect.
