Hamiltonian description of singular Lagrangian systems with spontaneously broken time translation symmetry
Liu Zhao, Pengfei Yu, Wei Xu
Shapere and Wilczek recently found some singular Lagrangian systems which spontaneously breaks time translation symmetry. The common feature of their models is that the energy func…
