Discovering nonlinear resonances through physics-informed machine learning
G. D. Barmparis, G. P. Tsironis
For an ensemble of nonlinear systems that model, for instance, molecules or photonic systems, we propose a method that finds efficiently the configuration that has prescribed trans…
Estimating the infection horizon of COVID-19 in eight countries with a data-driven approach
G. D. Barmparis, G. P. Tsironis
The COVID-19 pandemic has affected all countries of the world producing a substantial number of fatalities accompanied by a major disruption in their social, financial, and educati…
Pattern formation and chimera states in 2D SQUID metamaterials
Johanne Hizanidis, Nikos Lazarides, Giorgos P. Tsironis
The Superconducting QUantum Interference Device (SQUID) is a highly nonlinear oscillator with rich dynamical behavior, including chaos. When driven by a time-periodic magnetic flux…
Point interactions with bias potentials
A. V. Zolotaryuk, G. P. Tsironis, Y. Zolotaryuk
We develop an approach on how to define single-point interactions under the application of external fields. The essential feature relies on an asymptotic method based on the one-po…
Chimera states in networks of locally and non-locally coupled SQUIDs
J. Hizanidis, N. Lazarides, G. P. Tsironis
Planar and linear arrays of SQUIDs (superconducting quantum interference devices), operate as nonlinear magnetic metamaterials in microwaves. Such {\em SQUID metamaterials} are par…
Controlled Generation of Chimera States in SQUID Metasurfaces using DC Flux Gradients
N. Lazarides, J. Hizanidis, G. P. Tsironis
SQUID (Superconducting QUantum Interference Device) metamaterials, subject to a time-independent (dc) flux gradient and driven by a sinusoidal (ac) flux field, support chimera stat…
