Which Coherence Decoheres? Basis-Dependent Decoherence Rates in Symmetry-Broken Collective Spin Systems

In the ordered phase of a Z 2-symmetric collective spin system, two natural bases -- localised pointer states \|P rangle ,|R rangle \ and energy eigenstates \|E 0 rangle ,|E 1 rangle \ -- yield Lindblad dephasing rates that differ by a f...
