Activated switching between coexisting limit cycles
Gabriel Margiani, Orjan Ameye, Oded Zilberberg +1
Noise-activated switching between coexisting stable states is a fundamental mechanism underlying stochastic dynamics in systems ranging from chemical reactions to neural networks.…
Nonequilibrium Kramers Turnover in a Kerr Parametric Oscillator
Daniel K. J. Boneß, 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…
Dynamical Phase Transitions Across Slow and Fast Regimes in a Two-Tone Driven Duffing Resonator
Soumya S. Kumar, Javier del Pino, Letizia Catalini +2
The response of nonlinear resonators to multifrequency driving reveals rich dynamics beyond conventional single-tone theory. We study a Duffing resonator under bichromatic excitati…
A network of parametrically driven silicon nitride mechanical membranes
Luis Mestre, Suyash Singh, Gabriel Margiani +3
Networks of nonlinear resonators offer a promising platform for analog computing and the emulation of complex systems. However, realizing such networks remains challenging, as it r…
Three Strongly Coupled Kerr Parametric Oscillators Forming a Boltzmann Machine
Gabriel Margiani, Orjan Ameye, Oded Zilberberg +1
Coupled Kerr parametric oscillators (KPOs) are a promising resource for classical and quantum analog computation, for example to find the ground state of Ising Hamiltonians. Yet, t…
The parametric instability landscape of coupled Kerr parametric oscillators
Orjan Ameye, Alex Eichler, Oded Zilberberg
Networks of coupled Kerr parametric oscillators (KPOs) hold promise as for the realization of neuromorphic and quantum computation. Yet, their rich bifurcation structure remains la…
Slow and fast topological dynamical phase transitions in a Duffing resonator driven by two detuned tones
Letizia Catalini, Javier del Pino, Soumya S. Kumar +4
The combination of a strong pump and a weak probe has been widely applied to investigate both optical and nanomechanical devices. Such pump-probe measurements allows for the explor…
Topological classification of driven-dissipative nonlinear systems
Greta Villa, Javier del Pino, Vincent Dumont +4
In topology, one averages over local geometrical details to reveal robust global features. This approach proves crucial for understanding quantized bulk transport and exotic bounda…
The Stochastic Guitar
Andreas Eggenberger, Alexander Eichler
Stochastic physics is a central pillar of modern research in many fields, but is rarely presented to undergrad students in a hands-on experiment. Here, we demonstrate how a human-s…
Hamiltonian reconstruction via ringdown dynamics
Vincent Dumont, Markus Bestler, Letizia Catalini +3
Many experimental techniques aim at determining the Hamiltonian of a given system. The Hamiltonian describes the system's evolution in the absence of dissipation, and is often cent…
Gate-controlled phase switching in a Parametron
Z. Nosan, P. Marki, N. Hauff +2
The parametron, a resonator-based logic device, is a promising physical platform for emerging computational paradigms. When the parametron is subject to both parametric pumping and…
