Time evolution for the Pauli-Fierz operator (Markov approximation and Rabi cycle)
Laurent Amour, Jean Nourrigat
This article is concerned with a system of particles interacting with the quantized electromagnetic field (photons) in the non relativistic Quantum Electrodynamics (QED) framework…
Classical and quantum energies for interacting magnetic systems
Laurent Amour, Jean Nourrigat
The purpose of this article is to give different interpretations of the first non vanishing term (quadratic) of the ground state asymptotic expansion for a spin system in quantum e…
Lindblad approximation and spin relaxation in quantum electrodynamics
Laurent Amour, Jean Nourrigat
This article is concerned with the time evolution of a -spin particle in a constant external magnetic field with the quantized electromagnetic field (photons). We deri…
Ground state photon number at large distance
Laurent Amour, Lisette Jager, Jean Nourrigat
The purpose of this article is to give a result of localization in space of the ground states photons, in some sense, of a Hamiltonian modelling nuclear magnetic resonance in quant…
Composition of states and observables in Fock spaces
Laurent Amour, Lisette Jager, Jean Nourrigat
This article is concerned with compositions in the context of three standard quantizations in the Fock space framework, namely, anti-Wick, Wick and Weyl quantizations. The first on…
On the domain of a magnetic Schrödinger operator with complex electric potential
B Helffer, Jean Nourrigat
The aim of this paper is to review and compare the spectral properties of (the closed extension of) -- + U (V 0) and -- + iV in L 2 (R^d) for C real potentials…
