Lie-Schwinger block-diagonalization and gapped quantum chains: analyticity of the ground-state energy
S. Del Vecchio, J. Fröhlich, A. Pizzo +1
We consider quantum chains whose Hamiltonians are perturbations by interactions of short range of a Hamiltonian that does not couple the degrees of freedom located at different sit…

Lie-Schwinger block-diagonalization and gapped quantum chains with unbounded interactions
S. Del Vecchio, J. Fröhlich, A. Pizzo +1
We study quantum chains whose Hamiltonians are perturbations by interactions of short range of a Hamiltonian that does not couple the degrees of freedom located at different sites…

Coulomb scattering in the massless Nelson model IV. Atom-electron scattering
Wojciech Dybalski, Alessandro Pizzo
We consider the massless Nelson model with two types of massive particles which we call atoms and electrons. The atoms interact with photons via an infrared regular form-factor and…
