Spectral theory for a mathematical model of the weak interaction: The decay of the intermediate vector bosons W+/-. I

Autor: Barbaroux, J. -M., Guillot, J. -C.

Publikováno v: Adv.Math.Phys.2009:978903,2009

We consider a Hamiltonian with cutoffs describing the weak decay of spin one massive bosons into the full family of leptons. The Hamiltonian is a self-adjoint operator in an appropriate Fock space with a unique ground state. We prove a Mourre estimat

The dressed nonrelativistic electron in a magnetic field

Autor: Amour, L., Grebert, B., Guillot, J. -C.

We consider a nonrelativistic electron interacting with a classical magnetic field pointing along the $x_{3}$-axis and with a quantized electromagnetic field. When the interaction between the electron and photons is turned off, the electronic system

On Effective Hamiltonians for Adiabatic Perturbations of Magnetic Schrodinger Operators

Autor: Dimassi, M., Guillot, J. -C., Ralston, J.

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 Hamiltonian. We assume that the magnetic and electric potentials are s

Quantum electrodynamics of relativistic bound states with cutoffs

Autor: Barbaroux, J. -M., Dimassi, M., Guillot, J. -C.

We consider an Hamiltonian with ultraviolet and infrared cutoffs, describing the interaction of relativistic electrons and positrons in the Coulomb potential with photons in Coulomb gauge. The interaction includes both interaction of the current dens
