Online training of Echo State Networks to predict chaotic dynamical systems
Astero Provata, Markos Syroukis, Johanne Hizanidis
Echo State Networks (ESNs) are fundamentally important from the conceptual perspective of AI, because they provide simple and tractable frameworks for understanding temporal inform…
Reservoir Computing with a single Josephson junction
George Baxevanis, Kathy Lüdge, Johanne Hizanidis
Physical reservoir computing exploits the nonlinear dynamics of a physical system to perform information processing tasks. Josephson junctions (JJs), as nonlinear superconducting d…
Multi-branched resonances, chaos through quasiperiodicity, and asymmetric states in a superconducting dimer
Joniald Shena, Nikos Lazarides, Johanne Hizanidis
A system of two identical SQUIDs (superconducting quantum interference devices) symmetrically coupled through their mutual inductance and driven by a sinusoidal field is investigat…
Localized patterns in star networks of Class B lasers with optoelectronic feedback
Joniald Shena, Johanne Hizanidis, Nikos E. Kouvaris +1
We analyze how a star network topology shapes the dynamics of coupled CO\textsubscript{2} lasers with an intracavity electro-optic modulator that exhibit bistability. Such a networ…
Flux bias-controlled chaos and extreme multistability in SQUID oscillators
Johanne Hizanidis, Nikos Lazarides, George Tsironis
The radio frequency (rf) Superconducting QUantum Interference Device (SQUID) is a highly nonlinear oscillator exhibiting rich dynamical behavior. It has been studied for many years…
Chimera states and synchronization in magnetically driven SQUID metamaterials
J. Hizanidis, N. Lazarides, G. Neofotistos +1
Superconducting QUantum Interference Device (SQUID) metamaterials are superconducting artificial media whose function relies both on their geometry and the extraordinary properties…
