abstract = {Virtual materials design attempts to use computational
methods to discover new materials with superior properties
within the vast space of all conceivable materials.
Density-functional theory (DFT) is central to this field,
enabling scientists to predict material properties from
first principles, i.e. without relying on external
parameters or experimental values. While standard DFT is
capable of predicting many materials with satisfying
accuracy, it struggles with some properties such as details
of the electronic structure or certain material classes,
e.g. materials exhibiting strongly correlated electrons.
This has created a need for methods with greater predictive
power. One such class of methods are hybrid
exchange-correlation functionals which combine the exact
Hartree-Fock exchange with local exchange-correlation
functionals, resulting in highly accurate predictions for
many insulating or semiconductor materials. However, the
computational cost of hybrid functionals increases rapidly
with system size and limits their application to small
systems. This thesis aims to solve the computational
challenge posed by hybrid functionals in large systems by
utilizing the massive computational power of today’s
supercomputers},
