PCoMS & RISME TOMBO Seminar:First-Principles Theory, Computation, and Hands-On 2022

details & application form

 

This seminar is for anyone, who is interested in the first-principles code, TOMBO. TOMBO uses the all-electron mixed basis approach, in which one-electron orbitals are expressed with both plane waves and atomic orbitals. TOMBO can handle both isolated systems and crystal (or periodic) systems in a unified way. It can perform not only LDA calculations but also GW (+ Bethe-Salpeter equation) calculations. It also handles the TDDFT dynamics simulations in the excited states as well as the usual first-principles molecular dynamics (MD) simulations in the ground state. The hands-on tutorial is about 2 and half hours including (1) GW+Bethe-Salpeter calculation for Li_2, (2) LDA band calculation for Si crystal, (3) first-principles MD simulation for the chemical reaction CO_2 +2H → HCOOH, and (4) GW calculation for Si crystal.
