    "abstract": "We investigate the connection between quasi-classical (pointer) states and\ngeneralized coherent states (GCSs) within an algebraic approach to Markovian\nquantum systems (including bosons, spins, and fermions). We establish\nconditions for the GCS set to become most robust by relating the rate of purity\nloss to an invariant measure of uncertainty derived from quantum Fisher\ninformation. We find that, for damped bosonic modes, the stability of canonical\ncoherent states is confirmed in a variety of scenarios, while for systems\ndescribed by (compact) Lie algebras stringent symmetry constraints must be\nobeyed for the GCS set to be preferred. The relationship between GCSs,\nminimum-uncertainty states, and decoherence-free subspaces is also elucidated.",
