Given a pure quantum state ψ of a many-body system S = L ∪ R, consistingP of two subD systems L and R, the EE is defined as S = − i λi ln λi , where {λi }, i = 1, ..., D, are the eigenvalues of the reduced density matrix ρ̂R ...

At the classical level, we find this unlikely to occur. However, one could argue that considering the Universe conformal factor as an external parameter ...
