Non-Gaussianity in the quantum parametric oscillator

M Calvanese Strinati, C Conti - Physical Review A, 2024 - APS
Systems of coupled optical parametric oscillators (OPOs) forming an Ising machine are
emerging as large-scale simulators of the Ising model. The advances in computer science …

Dynamical phase transitions in the non-reciprocal Ising model

Y Avni, M Fruchart, D Martin, D Seara… - arXiv preprint arXiv …, 2024 - arxiv.org
Non-reciprocal interactions in many-body systems lead to time-dependent states, commonly
observed in biological, chemical, and ecological systems. The stability of these states in the …

Using continuation methods to analyse the difficulty of problems solved by Ising machines

J Lamers, G Verschaffelt, G Van der Sande - Communications Physics, 2024 - nature.com
Ising machines are dedicated hardware solvers of NP-hard optimization problems. However,
they do not always find the most optimal solution. The probability of finding this optimal …

Energy landscape and flow dynamics measurements of driven-dissipative systems

V Dumont, M Bestler, L Catalini, G Margiani… - Physical Review …, 2024 - APS
Many experimental techniques aim at determining the energy landscape of a system given
and compare it to a model Hamiltonian. This landscape governs the system's evolution in …

Coupled parametric oscillators: From disorder-induced current to asymmetric Ising model

C Han, M Wang, B Zhang, MI Dykman, HB Chan - Physical Review Research, 2024 - APS
We study the effects of the interplay of weak disorder and weak coupling in a system of
parametric micromechanical oscillators. Each oscillator is bistable, enabling the mapping of …

Hamiltonian reconstruction via ringdown dynamics

V Dumont, M Bestler, L Catalini, G Margiani… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …
