When light interacts with nanostructures, new effects and phenomena arise in comparison to the light-matter interaction with bulk. Examples are modified optical responses and sharp resonances or a coherent driving of quantum systems. In turn, also the light field can be manipulated by nanostructured solids resulting in light focussing or amplitude enhancements. In this lecture we start by covering the basics of light-matter interaction. Then we will consider state-of-the-art examples of light-matter interaction in both semiconductor and metal nanostructures. Topics will include among others:
- Light matter interaction: dielectric function, minimal coupling Hamiltonian, dipole approximation, rotating wave approximation
- Metal nanostructures: Drude model, surface plasmon polaritons, nano-plasmonics, numerical methods
- Semiconductor nanostructures: band structure, dipole selection rules, quantum dots, optical control
