Noise-resilient point-based sensors enabled by nonlinearities

This mixed-mode seminar allowed for both in-person participation in the graduate classroom and virtual participation through a Google Meet link.

Arunn Suntharalingam is a young PhD candidate with a brilliant career and a promising future. Originally from Malaysia, he graduated in 2021 with a Bachelor of Science degree in Astrophysics from the University of Minnesota (Twin-Cities). He is currently pursuing his third year of a PhD in Physics at Wesleyan University, Connecticut, under the direction of Prof. Tsampikos Kottos. He also collaborates with Drs. Alba Ramos and Lucas Fernandez from the Institute for Modeling and Technological Innovation (IMIT).

Suntharalingam's PhD topic focuses on ultrasensitive sensors and devices with increased response in non-Hermitian and non-linear systems that exploit appropriate handling of symmetry. His most notable achievement to date has been the development of a noise-resistant hypersensitive sensor prototype in a PT-symmetric configuration, which was experimentally demonstrated and published in the prestigious journal Nature Communications14, 5515 (2023).
