• Abstract: We revisit quantum-classical hybrid systems of the Sudarshan type under the light of Galilean covariance. We show that these kind of hybrids cannot be given as a unitary representation of the Galilei group and at the same time conserve the total linear momentum unless the interaction term only depends on the relative canonical velocities.

  We arrive at a consistent, nonstandard representation of the Galilei group. The corresponding quantum (and classical) theory shares with the relativistic one their fundamentals. The tachyonic objects described by the new representation cannot be regarded as localizable in the standard sense.

  We find that hitherto unrecognized quasiparticles -- incoherentons -- describe a coherent-to-incoherent transition in eigenmodes of a Liouvillian superoperator. We demonstrate the existence of incoherentons in a lattice boson model subject to dephasing, and show that the quantum coherence gap closes when incoherentons are deconfined.

  A unitary irreducible non-projective representation of the Galilei group is possible in the Koopman-von Neumann formulation of classical mechanics. We show, by direct construction, that classical mechanics also allows for a projective representation of the Galilei group where the mass is the central charge of the algebra.
