Dual-state control of lasing and absorption via conjugate exceptional points
Arnab Laha, Somnath Ghosh, Adam Miranowicz +1
Lasing and coherent perfect absorption (CPA) are time-reversed manifestations of non-Hermitian light-matter interactions. While exceptional points (EPs) have been extensively explo…
Dynamically Encircled Higher-order Exceptional Points in an Optical Fiber
Arpan Roy, Arnab Laha, Abhijit Biswas +3
The unique properties of exceptional point (EP) singularities, arising from non-Hermitian physics, have unlocked new possibilities for manipulating light-matter interactions. A tai…
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…
