Observation of a phase shift in nonlinear parity-time symmetric film bulk acoustic resonators

Physical Review Research
An exceptional point (EP) in PT (parity-time)-symmetric systems featuring loss and nonlinear saturable gain has been recently utilized to enhance sensing, leading to the cube-root singularity in a two-level system.

Film Bulk Acoustic Resonators for Nitrogen Monoxide Detection at 250 °C

Proceedings
Exposure to hazardous gases like NOx can have a negative impact on our health. High-performance sensors are needed to control high levels of these contaminants, which, in most cases, are generated by automotive exhaust or industrial factories.
