\nInternational School on Ab initio Modelling of Solids with CRYSTAL14 (ISAMS2014)<\/em>
\nRegensburg, Germany, July 24, 2014<\/p>\n

Lecture at the ISAMS2014 summer school on the application of solid-state quantum chemistry to spin center systems within DFG SFB813 Collaborative Research Area Project C5. Covers the use of the CRYSTAL code to investigate stacked organic radical cations and the role of periodic boundary conditions in studying spin-center interactions in molecular solids.\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n

\nRegensburg, Germany, July 21, 2014<\/p>\n

Lecture on the pob-TZVP solid-state Gaussian basis sets at the ISAMS2014 summer school. Introduces the motivation for specialized solid-state basis sets derived from molecular Ahlrichs def2-TZVP standards, the reoptimization strategy for robust SCF convergence, and benchmark performance across ionic insulators, semiconductors, and transition-metal oxides.\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\nChemnitz, Germany, November 15, 2013<\/p>\n

Invited seminar presenting the AICCM implementation: the theoretical framework of the cyclic Born–von-Kármán boundary conditions and Wigner–Seitz supercells, the new weighting schemes for three- and four-center integrals, the AICCM program architecture, and validation comparing AICCM to CRYSTAL09 for one-dimensional periodic hydrogen chains.\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n

Invited lecture at the MSSC2013 school (September 1–5, 2013), delivered Monday September 2 at 9:40 AM. Presents the pob-TZVP basis set series: derivation from molecular def2-TZVP, exponent reoptimization for solid-state convergence, and comprehensive benchmarks on lattice constants and thermochemistry for ionic, semiconducting, and covalent test sets.\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
