Who Should Attend
Graduate students, postdocs, and other scientists interested in learning about the essential elements of Density Functional Theory, both in its ground-state and time-dependent formulations. The tutorial talks will be very pedagogical, covering the fundamentals of the theory and a few applications, latest developments, and unsolved questions. This tutorial will be a good introduction for those who are planning to attend the electronic-structure focused sessions at this APS meeting.
Density Functional Theory (DFT) provides a practical route for calculating the electronic structure of matter at all levels of aggregation. More than five decades after its inception, it is now routinely used in many fields of research, from materials engineering to drug design. Time-dependent Density Functional Theory (TDDFT) has extended the success of DFT to time-dependent phenomena and excitations. Most applications are carried out in the linear-response regime to describe molecular excitations, but the theory is applicable to a much broader class of problems, including strong-field phenomena, attosecond control of electron dynamics, nanoscale transport, and non-adiabatic dynamics of coupled electron-nuclear systems. The tutorial will provide an introduction to the basic formalism of DFT and TDDFT, an overview of state-of-the-art functionals and applications, and a discussion of the most pressing open questions.
