Universal sign-control of coupling in tight-binding lattices
Robert Keil, Charles Poli, Matthias Heinrich +4
We present a method of locally inverting the sign of the coupling term in tight-binding systems, by means of inserting a judiciously designed ancillary site and eigenmode matching…

Parity-time-symmetric coupled microring lasers operating around an exceptional point
Hossein Hodaei, M. Ali Miri, Absar Ul Hassan +4
The behavior of a parity-time (PT) symmetric coupled microring system is studied when operating in the vicinity of an exceptional point. Using the abrupt phase transition around th…
