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.…
Few-photon degenerate parametric resonance in a two-tone driven microwave resonator
Orjan Ameye, Jakob Koenig, Clinton Potts +2
Multi-tone external driving offers a route to parametric physics without directly modulating the device. However, the validity of the parametric response in the few-photon regime 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…
Fluctuation instabilities via internal resonance in a multimode membrane as a mechanism for frequency combs
Mengqi Fu, Orjan Ameye, Fan Yang +4
We explore self-induced parametric coupling, also called internal resonances (IRs), in a membrane nanoelectromechanical system. Specifically, we focus on the formation of a limit c…
Path Integral Monte Carlo Simulation of Superfluid Ring Lattices
Orjan Ameye
The goal of this work is to lay the groundwork to construct and characterize a quantum device; which we refer to as a superfluid ring lattice; that could serve as a multi-qubit sys…
Floquet expansion by counting pump photons
Kilian Seibold, Orjan Ameye, Oded Zilberberg
Periodically-driven systems engender a rich competition between the time scales of the drives and those of the system, leading to a limited ability to describe the system in full.…
