Quantum topological phase transitions in skyrmion crystals
(Peer reviewed; Journal article, 2022)Topological order is important in many aspects of condensed matter physics and has been extended to bosonic systems. In this Letter we report on the nontrivial topology of the magnon bands in two distinct quantum skyrmion ... -
Schwinger boson study of superconductivity mediated by antiferromagnetic spin fluctuations
(Peer reviewed; Journal article, 2020)We study superconductivity in a normal metal, arising from effective electron-electron interactions mediated by spin fluctuations in a neighboring antiferromagnetic insulator. Introducing a frustrating next-nearest neighbor ...
