The role of atomic interactions in cavity-induced continuous time crystals

CH Johansen, J Lang, F Piazza - SciPost Physics, 2024 - scipost.org
We consider continuous time-crystalline phases in dissipative many-body systems of atoms
in cavities, focusing on the role of short-range interatomic interactions. First, we show that …

[HTML][HTML] Smooth transformations and ruling out closed orbits in planar systems

T Pedergnana, N Noiray - Chaos: An Interdisciplinary Journal of …, 2023 - pubs.aip.org
This work deals with planar dynamical systems with and without noise. In the first part, we
seek to gain a refined understanding of such systems by studying their differential-geometric …

Fluctuation instabilities via internal resonance in a multimode membrane as a mechanism for frequency combs

M Fu, O Ameye, F Yang, J Košata, J del Pino… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …

Floquet expansion by counting pump photons

K Seibold, O Ameye, O Zilberberg - arXiv preprint arXiv:2404.09704, 2024 - arxiv.org
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. We …

Adiabatic and diabatic responses in a Duffing resonator driven by two detuned tones

L Catalini, J del Pino, SS Kumar, V Dumont… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …

Certain features of planar systems

T Pedergnana, N Noiray - arXiv preprint arXiv:2309.02513, 2023 - arxiv.org
This work is concerned with features of planar dynamical systems governed by a smooth
velocity field and additive white noise. By Helmholtz's theorem, the system's velocity field …
