On Effective Hamiltonians for Adiabatic Perturbations of Magnetic Schrodinger Operators
M. Dimassi, J. -C. Guillot, J. Ralston
We construct almost invariant subspaces and the corresponding effective Hamiltonian for magnetic Bloch bands. We also discuss the question of the dynamics related to the effective…

Quantum electrodynamics of relativistic bound states with cutoffs
J. -M. Barbaroux, M. Dimassi, J. -C. Guillot
We consider an Hamiltonian with ultraviolet and infrared cutoffs, describing the interaction of relativistic electrons and positrons in the Coulomb potential with photons in Coulom…
