General perturbation theory for local quantum uncertainty and its formulation in the linear-response regime
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.

Quantum magic of strongly correlated fermions $-$ the Hubbard dimer
Non-stabilizerness of the Hubbard dimer is computed with robustness of magic and stabilizer Rényi entropy, revealing it as a resource distinct from fermionic non-Gaussianity and superselected entanglement.
