Complexity and multi-functionality of superconducting meta-materials

uper conductingmeta-materials are ultralow loss, artificial, man-mademedia which are designed to achieve properties
not available in natural materials. SQUID (Super conducting Quantum Interference Device) based metamaterials
have additional functionality and control properties with exciting new collective properties both in the classical and
quantum realms. A SQUID is a unique non-linear oscillator that can be manipulated through multiple external means.
This domain flexibility is retained by SQUID based metamaterials and meta-surfaces i.e., extended units that contain
a large arrangement of SQUIDs in various interaction configurations. Such units are essentially assemblies of weakly
coupled nonlinear oscillators where numerous, classical as well as quantum complex, spatio temporal phenomena may
be explored. In this presentation we will focus on SQUID based metamaterials and present basic properties related
to their individual and collective responses to external drives. We will show that a SQUID based system acts as a
genuine meta material with right as well as left handed properties; demonstrate that Josephson nonlinearity leads to
wide band tunability, intrinsic nonlinear as well as flat band localization. We will further present exciting dynamical
response properties such as multi stability and self-organization and the emergence of counter intuitive chimera states of
selective, partial organization. In the truly quantum regime we will explore the interaction of electromagnetic pulses with
superconducting qubit units where the coupling between the two yields properties such as self-induced transparency
and super radiance. The appearance of these complex phenomena will be linked to possible technological applications.
