Quantum Condensed Matter Photonics @ NKUA

Welcome to our group! We are with the Section of Condensed Matter Physics  of the Department of Physics  at the National and Kapodistrian University of Athens  (NKUA). We conduct theoretical, computational, and experimental research in the broader area of quantum condensed matter photonics, including nanophotonics, metamaterials, "slow-" and "fast-light" phenomena, invisibility cloaking, laser physics, (quantum) self-organized criticality, topological, chiral and nonlinear optics, and computational electrodynamics. We aim at advancing, both, fundamental knowledge and, in collaboration with our international partners, conceiving practical applications in the above scientific fields by exploring advanced new optical, electromagnetic, magnetic / topological, chiral, and quasi-2D materials and devices.
