If real is what you can feel, smell, taste and see, then 'real' is simply electrical signals interpreted by your brain.

For simple uses, use By default, The eigenvalue correlation_length_per_unit_cell = -1 / ln(|d|) To get the correlation length per site, multiply by the unit cell size. If the wavefunction is parity symmetric, then the transfer operator is Hermitian and the eigenvalues will be purely real. An imaginary component means that parity symmetry is broken, which may occur either if the Hamiltonian was not parity symmetric to begin with (eg, the Kagome strip), or if the parity symmetry breaks spontaneously, eg due to a long-range chiral order. This is all that is required for simple uses. |
