A general perturbation theory for local quantum uncertainty is derived and applied in linear response to show that driving frequency can resonantly enhance quantum discord without entanglement in a two-spin Heisenberg model.
Fock-state lattices are built from Lie-algebra generators, linking their structure and dynamics to phase-space geometry and revealing when integrable Hamiltonians lack such an algebraic origin.
Additional spin-orbital degrees of freedom produce strong thermal and quantum fluctuations that stabilize disordered nematic phases in the extended Kitaev-Yao-Lee model.
