Optimal Sensing of Momentum Kicks with a Feedback-Controlled Nanomechanical Resonator
Kaspar Schmerling, Hajrudin Bešić, Andreas Kugi +2
External disturbances exciting a mechanical resonator can be exploited to gain information on the environment. Many of these interactions manifest as momentum kicks, such as the re…

Optimized Signal Estimation in Nanomechanical Photothermal Sensing via Thermal Response Modelling and Kalman Filtering
Hajrudin Bešić, Andreas Deutschmann-Olek, Kenan Mešić +2
We present an advanced thermal response model for micro- and nanomechanical systems in photothermal sensing, designed to balance speed and precision. Our model considers the two ti…
