Lie-Schwinger block-diagonalization and gapped quantum chains: analyticity of the ground-state energy

Autor: Del Vecchio, S., Fröhlich, J., Pizzo, A., Rossi, S.

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 sites of the chain and has a strictly positive energy gap above its groun

Lie-Schwinger block-diagonalization and gapped quantum chains with unbounded interactions

Autor: Del Vecchio, S., Fröhlich, J., Pizzo, A., Rossi, S.

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 of the chain and has a strictly positive energy gap above its ground-s
