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…
Symmetry restoration through chaotic hysteresis in a non-Hermitian optical trimer
Johanne Hizanidis, Konstantinos G. Makris
We investigate symmetry restoration and spatially localized dynamics in a non-Hermitian optical trimer composed of three lossy waveguides with complex-valued couplings. Extending o…
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…
Effects of Strong Capacitive Coupling Between Meta-Atoms in rf SQUID Metamaterials
Jingnan Cai, Robin Cantor, Johanne Hizanidis +2
We consider, for the first time, the effects of strong capacitive and inductive coupling between radio frequency Superconducting Quantum Interference Devices (rf SQUIDs) in an over…
Coexisting periodic attractors under the influence of noise in injected photonic oscillators
Johanne Hizanidis, Vassilios Kovanis
The optical power spectrum is the prime observable to dissect, understand and design the long-time behavior of arrays of optically coupled semiconductor lasers. A long-standing iss…
Dynamical properties of neuromorphic Josephson junctions
Dimitrios Chalkiadakis, Johanne Hizanidis
Neuromorphic computing exploits the dynamical analogy between many physical systems and neuron biophysics. Superconductor systems, in particular, are excellent candidates for neuro…
