Ph.D. Thesis

My Ph.D. Thesis is titled Reduced Density Matrix Inspired Approaches to Electronic Structure Theory is available at figshare but you can have a glimpse below.

The work presented in the thesis was done in the Section of Theoretical Chemistry at the VU University in Amsterdam and Center for Superfunctional Materials at Pohang University of Science and Technology (POSTECH) in Pohang, South Korea.

The thesis was supervised by Prof. E. J. Baerends and Dr O. V. Gritsenko.
