Abstract :

We will present our recent developments in  the realisation of ultrasensitive vectorial force field sensors based on suspended silicon carbide nanowires, at room  [1] and dilution temperatures and analyse the impact of non-conservative  (rotational) force fields on their dynamics:  leading to eigenmode orthogonality breaking, noise reduction and violation of the fluctuation dissipation relation [2].
