You wrote "A Galilean "boost"? If you mean a Galilean transformation, since the Hamiltonian of a system is its total energy, invariant Hamiltonian means unchanging energy- that's conservation of energy." 1) In theoretical physics sometimes the G.transformation is called the "Galilean...

Hamiltonian under Galilean boost Norman correct only partially and only in part when he refers to the center of mass. In fact, if we consider the Hamiltonian for a system of free particles, then invariance of such a Hamiltonian under the Galilean boost would mean that the center of mass of the...
