Sparse identification of quasipotentials via a combined data-driven method
Bo Lin, Pierpaolo Belardinelli
The quasipotential function allows for comprehension and prediction of the escape mechanisms from metastable states in nonlinear dynamical systems. This function acts as a natural…

Hidden vibrational bistability revealed by intrinsic fluctuations of a carbon nanotube
P. Belardinelli, W. Yang, A. Bachtold +2
We demonstrate that a quiet state and large-amplitude self-sustained oscillations can co-exist in a carbon nanotube subject to time-independent drive. A feature of the bistability…
