Foundations of Many-Body Theory
-
GW and Bethe-Salpeter calculations of the optical response of extended and low dimensional systems.
-
Construction of exchange-correlation kernels for TDDFT based on MBPT.
-
New orbital-dependent functionals based on variational total energy functionals (for more details see our recent work in this field).
See this lectures notes given in the School on "Time-Dependent Density-Functional Theory and the Dynamics of Complex Systems" St. John's College, Santa Fe, New Mexico (USA) (5-10 June 2004) for a summary of our recent work.
