Chimeras in squid metamaterials

Lazarides, N.; Neofotistos, G.; Tsironis, G. P. (Nazarbayev University, 2014)

Non-locally coupled, periodically arranged SQUIDs (Superconducting QUantum Interference Devices) can form magnetic metamaterials exhibiting extraordinary properties, including tuneability and dynamic multistability, which ...
Chimera states and synchronization in magnetically driven SQUID metamaterials

Hizanidis, J.; Lazarides, N.; Neofotistos, G.; Tsironis, G. P. (European Physical Journal: Special Topics, 2016-09-01)

One-dimensional arrays of Superconducting QUantum Interference Devices (SQUIDs) form magnetic metamaterials exhibiting extraordinary properties, including tunability, dynamic multistability, negative magnetic permeability, ...
Enhanced surface plasmon polariton propagation induced by active dielectrics

Athanasopoulos, C.; Mattheakis, M.; Tsironis, G. P. (Nazarbayev University, 2014)

We present numerical simulations for the propagation of surface plasmon polaritons (SPPs) in a dielectric-metal-dielectric waveguide using COMSOL multiphysics software. We show that the use of an active dielectric with ...
Linear and non-linear photonic rogue waves in complex transparent media

Mattheakis, M.; Pitsios, I. J.; Tsironis, G. P.; Tzortzakis, S. (Nazarbayev University, 2014)

Ocean rogue waves (RW) -huge solitary waves- have for long triggered the interest of scientists. RWs emerge in a complex environment and it is still unclear if their appearance is due to linear or nonlinear processes. ...
Robust chimera states in SQUID metamaterials with local interactions

Hizanidis, J.; Lazarides, N.; Tsironis, G. P. (Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2016-09-27)

We report on the emergence of robust multiclustered chimera states in a dissipative-driven system of symmetrically and locally coupled identical superconducting quantum interference device (SQUID) oscillators. The "snakelike" ...
Scattering properties of PT- symmetric layered periodic structures

Shramkova, O. V.; Tsironis, G. P. (Journal of Optics (United Kingdom), 2016-10-01)

The optical properties of PT-symmetric periodic stacks of the layers with balanced loss and gain are examined. We demonstrate that the tunnelling phenomenon in periodic structures is connected with excitation of surface ...
