Magnetic quantum phase transitions: 1/d expansion, bond-operator theory, and coupled-dimer magnets
In the study of strongly interacting condensed-matter systems controlled microscopic theories hold a key position. Spin-wave theory, large-N expansion, and $epsilon$-expansion are some of the few successful cornerstones. In this doctoral thesis work, we have developed a novel large-$d$ expansion met...
