The Peierls-Onsager Effective Hamiltonian in a complete gauge covariant setting: Description of the spectrum

Viorel Iftimie, Radu Purice

Using the procedures in \cite{Bu} and \cite{GMS} and the magnetic pseudodifferential calculus we have developped in \cite{MP1,MPR1,IMP1,IMP2} we construct an effective Hamitonian t…
