Relative entropy of coherent states on general CCR algebras
Henning Bostelmann, Daniela Cadamuro, Simone Del Vecchio
For a subalgebra of a generic CCR algebra, we consider the relative entropy between a general (not necessarily pure) quasifree state and a coherent excitation thereof. We give a un…
Compact Hypergroups from Discrete Subfactors
Marcel Bischoff, Simone Del Vecchio, Luca Giorgetti
Conformal inclusions of chiral conformal field theories, or more generally inclusions of quantum field theories, are described in the von Neumann algebraic setting by nets of subfa…
Local iterative block-diagonalization of gapped Hamiltonians: a new tool in singular perturbation theory
Simone Del Vecchio, Juerg Froehlich, Alessandro Pizzo +1
In this paper the local iterative Lie-Schwinger block-diagonalization method, introduced in [FP], [DFPR1], and [DFPR2] for quantum chains, is extended to higher-dimensional quantum…
