Non-local stabilizer entropies of fermionic Gaussian states admit a closed form from reduced Majorana covariance eigenvalues when minimized over local Gaussian unitaries.
Seeding boundary time crystals induces a measurement-induced phase transition where steady-state entanglement entropy scales with system size N in the seeded phase but decays exponentially otherwise.
