Unbounded Irreversibility at Fixed Low-Order Dynamics and Generator Spectrum

This paper establishes an exact mathematical counterexample showing that extensive agreement between the statistical and dynamical properties of finite-state stochastic systems does not determine their time-reversal irreversibility. A one-parameter family of irreducible, 20-state...

Z-boson pair entanglement against all separable states: a decay-angle witness for H → ZZ*

ATLAS has reported evidence of Z-boson pair entanglement in H → ZZ* → 4ℓ at 4.7σ (4.9σ expected) with 304 fb⁻¹. The separable hypothesis it tests is a single state, the pure product state |00⟩, which ATLAS describes as the only separable state consistent with its assumptions. Tha...
