|Title:||Foundations of Density Functional Theory Revisited|
|Seminar:||Computational and Applied Mathematics Colloquium|
|Speaker:||Paul Lammert, Physics Dept. PSU|
|This talk will be an exploration of the foundations of Density Functional Theory (DFT). Density Functional Theory is the basis of electronic structure
calculations of high accuracy at acceptable computational cost for systems of up to hundreds of atoms and thus has a wide and growing impact in physics, chemistry and materials science. Our emphasis, however, will be on DFT as a distinct viewpoint on quantum many-body systems interesting for its own sake.
There is some tendency to regard the foundations of the theory as a finished and straighforward story, but we will see that the structure is less sturdy and more unruly that one would like. To tame the troubles coming from arbitrarily short distance scales, we formulate a non-traditional "coarse-grained" approach
and show that it is well-behaved.|
