Synopsis:

The lecture offers a deep overview on nanophysics, clarifies the terminology, compares various forms of matter and structures, with the emphasis on nanostructures, and relates electronic and photonic nanostructures. It also reviews terms and methods form solid state physics, and applies them to quantum restricted nanostructures (quantum wells, multiple quantum wells, quantum wires, quantum dots). The attention is further given both to the electrodynamics of metals, its specifics, the lecture discusses and classifies plasmons; it further systematically explains especially the surface plasmons. Next, the lecture covers the photonic nanostructures, their properties, and relation to electronic structures, with the emphasis on photonic crystals, it gives their examples in 1D, 2D and 3D. The final attention is given to novel artificial materials, mainly metamaterials with negative refractive index. The course is concluded with the student presentations on selected given topics.
