Semiclassics for particles with spin via a Wigner-Weyl-type calculus
Omri Gat, Max Lein, Stefan Teufel
We show how to relate the full quantum dynamics of a spin-1/2 particle on R^d to a classical Hamiltonian dynamics on the enlarged phase space R^d x S^2 up to errors of second order…
Effective Light Dynamics in Perturbed Photonic Crystals
Giuseppe De Nittis, Max Lein
In this work, we rigorously derive effective dynamics for light from within a limited frequency range propagating in a photonic crystal that is modulated on the macroscopic level;…
Topological Polarization in Graphene-like Systems
Giuseppe De Nittis, Max Lein
In this article we investigate the possibility of generating piezoelectric orbital polarization in graphene-like systems which are deformed periodically. We start with discrete two…
The Perturbed Maxwell Operator as Pseudodifferential Operator
Giuseppe De Nittis, Max Lein
As a first step to deriving effective dynamics and ray optics, we prove that the perturbed periodic Maxwell operator in d = 3 can be seen as a pseudodifferential operator. This nec…
