In-situ Time-domain Physical Adjoint Optimization of Complex Wave Dynamics
Hoyeong Kwon, Arunn Suntharalingam, Laureano Bulus-Rossini +1
Direct optimization of complex wave dynamics through the intrinsic evolution of physical systems is fundamentally limited by the lack of directly accessible gradients. Adjoint meth…
Observed enhanced emission at higher-order exceptional points in RF circuits
Nicolas Wyszkowski, Arunn Suntharalingam, Max Vitek +3
The Purcell effect -- stemming directly from the celebrated Fermi's Golden Rule -- links the enhanced emissivity of an emitter to the local density of states (LDoS) of a surroundin…
Symmetry violation-driven hysteresis loops as measurands for noise-resilient sensors
Arunn Suntharalingam, Lucas Fernández-Alcázar, Pablo Fabián Wagner-Boián +3
Sublinear resonant deviations from an exceptional point degeneracy (EPD) has been recently promoted as a sensing scheme. However, there is still an ongoing debate whether the sensi…
Noise Resilient Exceptional-Point Voltmeters based on Neuromorphic functionalities
Arunn Suntharalingam, Lucas Fernández-Alcázar, Rodion Kononchuck +1
Exceptional point degeneracies (EPD) of linear non-Hermitian systems have been recently utilized for hypersensitive sensing. This proposal exploits the sublinear response that the…
