Local Gauss law and local gauge symmetries in QFT
Franco Strocchi
Local gauge symmetries reduce to the identity on the observables, as well as on the physical states (apart from reflexes of the local gauge group topology) and therefore their use…
Some Rigorous Results on Symmetry Breakings in Gauge QFT
Franco Strocchi
The extraordinary success of the Standard Model asks for a more rigorous control beyond the perturbative approach, which is affected by mathematical problems (interaction picture a…
Corrections to Wigner-Eckart Relations by Spontaneous Symmetry Breaking
Carlo Heissenberg, Franco Strocchi
The matrix elements of operators transforming as irreducible representations of an unbroken symmetry group are governed by the well-known Wigner-Eckart relations. In the case o…
Generalized criteria of symmetry breaking. A strategy for quantum time crystals
Carlo Heissenberg, Franco Strocchi
The aim of this paper is to propose a criterion of spontaneous symmetry breaking that makes reference to the properties of pure phases defined by a translationally invariant state.…
Symmetries of the dynamics and Noether theorem in classical mechanics
Franco Strocchi
The aim of this note is to discuss the relation between one-parameter continuous symmetries of the dynamics, defined on physical grounds, and conservation laws. In the Hamiltonian…
Existence of quantum time crystals
Franco Strocchi, Carlo Heissenberg
The existence of quantum time crystals is investigated and shown to be possible in pure phases defined by a state invariant under a group of space translations, as displayed by exp…
