Periodic Systems

• Getting started with periodic systems   How to perform some basic calculation using bulk silicon as an example.
• Wires and slabs   Use the flexibility of the real-space grid to treat systems that are periodic in only one or two dimensions.
• Optical spectra of solids   How to obtain an optical spectrum for a solid using a time-dependent calculation.
• Band structure unfolding   How to get the bandstructure of a supercell.
• High-harmonic generation in solids   How to obtain the high-harmonic spectrum of a periodic 1D chain of atoms.
• Cell relaxation in solids   How to perform geometry relaxation in periodic systems.
