From: Terminal-coupling induced critical eigenspectrum transition in closed non-Hermitian loops
Real eigenenergies in parallel-coupled NH chains with terminal coupling. (a) Real eigenvalues E of system of parallel-coupled NH chains with terminal coupling in Fig. 6a at size N. The values of the critical system sizes \(N_0\) to \(N_3\) obtained from Eqs. (30) to (33) are indicated. (b) The moduli of \(\beta _{(\textrm{A,B}),\pm }\) for system in (a) across the range of real eigenenergies E considered.
