Webboundary conditions; while these states do not conserve the traditional probability current, we introduce the PT-current which is preserved. The perfect transmission states appear as a special caseofthePT-symmetricscatteringstates. I. INTRODUCTION A. Twonon-Hermitiansystems: openquantumsystemsandPT-symmetricsystems WebThis is the Siegert boundary condition that the resonant state has only out-going waves away from the scatterer [6, 14, 23, 27]. In fact, the Siegert boundary condition not only supports the resonant states but all other possible discrete states including the bound states and the anti-resonant states, that is, all poles of the S matrix.
