Peierls substitution for magnetic Bloch bands
Silvia Freund, Stefan Teufel
We consider the Schrödinger operator in two dimensions with a periodic potential and a strong constant magnetic field perturbed by slowly varying non-periodic scalar and vector pot…

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…

Resonance phenomena in the interaction of a many-photon wave packet and a qubit
Omri Gat, Max Lein, Stefan Teufel
We demonstrate that a highly excited quantum electromagnetic mode strongly interacting with a single qubit exhibits several distinct resonances in addition to the Bloch-Siegert res…
