Functional renormalization group for frustrated quantum magnetism: method extension and material applications
Abstract: The field of highly frustrated magnetism harbors a wide variety of exotic phases that sustain interest in the field with no end in sight. Competing interactions yield models that often remain highly fluctuating down to zero temperature, have long-range entangled ground states, or exhibit fractionalized excitations. The study of these frustrated models presents a challenge for experimental and theoretical methods alike, driving their development in the process. As a contribution to the field, this thesis both further develops the pseudo-fermion functional renormalization group and applies the method in collaborative studies involving complementary methods to reveal low-temperature properties of a selection of frustrated spin models with relevance to spin compound families of recent interest.
