Extracting higher-order nonlinearities in nanomechanical resonators using the backbone relation
Maria Kallergi, Daniel K. J. BoneÃ, Maximilian Seitner +2
Nanomechanical resonators are a powerful platform for studying nonlinear dynamics with high sensitivity and precision. We explore the nonlinear response of a high-Q nanomechanical…
Nonequilibrium Kramers Turnover in a Kerr Parametric Oscillator
Daniel K. J. BoneÃ, Gabriel Margiani, Wolfgang Belzig +2
Activation processes govern noise-induced switching between long-lived states. In an equilibrium double well, the thermally activated switching rate exhibits a prefactor with a non…
Spectroscopy of Quantum Phase Slips: Visualizing Complex Real-Time Instantons
Foster Thompson, Daniel K. J. BoneÃ, Mark Dykman +1
Parametrically driven oscillators can emerge as a basis for the next generation of qubits. Classically, these systems exhibit two stable oscillatory states with opposite phases. Up…
Zero-temperature phase-flip rate in a biased parametric oscillator
Daniel K. J. BoneÃ, Wolfgang Belzig, Mark I. Dykman
A parametrically driven oscillator has two stable vibrational states at half the modulation frequency. The states have opposite phase and equal amplitudes. An extra drive at half t…
