Higher order topological degeneracies and towards unique successive state-switching in a four-level open system
Sayan Bhattacherjee, Harsh K. Gandhi, Arnab Laha +1
The physics of topological singularities, namely exceptional points (EPs), has been a key to wide range of intriguing and unique physical effects in non-Hermitian systems. In this…

Optical waveguide hosting multiple exceptional points: Toward selective mode conversion
Arnab Laha, Harsh K. Gandhi, Sibnath Dey +3
We investigate the astonishing physical aspects of Exceptional Points (EPs) in a 1D planar few-mode optical waveguide. The waveguide hosts four quasi-guided modes. Here interaction…
