Parametrically encircled higher-order exceptional points in anti-parity-time symmetric optical microcavities
Dinesh Beniwal, Arnab Laha, Adam Miranowicz +1
The fascinating realm of non-Hermitian physics with the interplay of parity (P) and time-reversal (T) symmetry has been witnessing immense attention in exploring unconventional phy…

Third-order Exceptional Point and Successive Switching among Three States in a Degenerate Optical Microcavity
Arnab Laha, Dinesh Beniwal, Sibnath Dey +2
One of the most intriguing topological features of open systems is exhibiting exceptional point (EP) singularities. Apart from the widely explored second-order EPs (EP2s), the expl…
