Chiral behaviour for three wave guides at an exceptional point of third order
WD Heiss, G Wunner
A simple matrix model that has been used to describe essential features of a PT symmetric set-up of three coupled wave guides is investigated. The emphasis of the study lies on the…

-symmetric wave guide system with evidence of a third-order exceptional point
Jan Schnabel, Holger Cartarius, Jörg Main +2
An experimental setup of three coupled -symmetric wave guides showing the characteristics of a third-order exceptional point (EP3) has been investigated in an idealiz…
