Summer school on Materials modeling from first principles: theory and practice, ICMR, University of California at Santa Barbara, July 19-31, 2009

The school will cover basic concepts and recent advances and developments. The former include ground-state calculations for isolated molecules and extended systems, pseudopotential theory and plane-wave basis sets, forces, stresses, and geometry and reaction-path optimizations, linear-response theory and phonons, and ab-initio molecular dynamics. Advanced techniques will include first-principles vibrational (IR, Raman) and magnetic (EPR, NMR) spectroscopies, electron-phonon and phonon-phonon interactions, excited states (TDDFT and GW), DFT+U and non-collinear magnetism, Wannier functions and quantum transport.
