Fermanian Kammerer, Clotilde Propagation of Wigner measures and degenerated codimension 1 crossings. (Propagation des mesures de Wigner à travers un croisement de codimension 1 dégénéré.) (French) Zbl 1178.35148 Sémin. Équ. Dériv. Partielles, Éc. Polytech., Cent. Math. Laurent Schwartz, Palaiseau 2007-2008, Exp. No. XXII, 10 p. (2008). The seminar presents some joint work of the author with T. Dyckaert and T. Jecko about the semi-classical Schrödinger operator \(P(\epsilon)=-\epsilon \Delta +V\), where the potential is a self-adjoint matrix. It is devoted to certain properties of the Wigner measures associated to a family of solutions of \(P(\epsilon)\psi^\epsilon=0\).
