Effective mass theorems with Bloch modes crossings
Victor Chabu, Clotilde Fermanian Kammerer, Fabricio Macià
We study a Schr{ö}dinger equation modeling the dynamics of an electron in a crystal in the asymptotic regime of small wavelength comparable to the characteristic scale of the cryst…
Pure and mixed states
J. C. A. Barata, M. Brum, V. Chabu +1
We present a review on the notion of pure states and mixtures as mathematical concepts that apply for both classical and quantum physical theories, as well as for any other theory…
Semiclassical analysis of dispersion phenomena
Victor Chabu, Clotilde Fermanian-Kammerer, Fabricio Macià
Our aim in this work is to give some quantitative insight on the dispersive effects exhibited by solutions of a semiclassical Schr{ö}dinger-type equation in R d. We describe quanti…
Wigner measures and effective mass theorems
Victor Chabu, Clotilde Fermanian-Kammerer, Fabricio Macià
We study a semi-classical Schr{ö}dinger equation which describes the dynamics of an electron in a crystal in the presence of impurities. It is well-known that under suitable assump…
Semiclassical analysis of the Schr{ö}dinger equation with conical singularities
Victor Chabu
In this article we study the propagation of Wigner measures linked to solutions of the Schr{ö}dinger equation with potentials presenting conical singularities and show that they ar…
