Gauging kinematical and internal symmetry groups for extended systems: the Galilean one-time and two-times harmonic oscillators
Roberto De Pietri, L. Lusanna, Massimo Pauri
The possible external couplings of an extended non-relativistic classical system are characterized by gauging its maximal dynamical symmetry group at the center-of-mass. The Galile…
