while studying lagrangian i got this doubt..if the lagrangian is invariant in time,space,rotation, then we have corresponding conservation laws..(adsbygoogle = window.adsbygoogle || []).push({});

In spontaneous symmetry breaking, the lagrangian is not invariant in ground state and the symmetry breaks spontaneously.so, the conserved quantity is now not conserved in ground state. so, are the conservation laws break in ground state?
