Fingerprints of Universal Spin-Stiffness Jump in Two-Dimensional Ferromagnets
(Peer reviewed; Journal article, 2020)Motivated by recent progress on synthesizing two-dimensional magnetic van der Waals systems, we propose a setup for detecting the topological Berezinskii-Kosterlitz-Thouless phase transition in spintransport experiments ... -
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 ... -
Thermal fluctuations and vortex lattice structures in chiral p-wave superconductors: Robustness of double-quanta vortices
(Peer reviewed; Journal article, 2021)We use large-scale Monte-Carlo simulations to study thermal fluctuations in chiral p-wave superconductors in an applied magnetic field in three dimensions. We consider the thermal stability of previously predicted unusual ... -
Zero temperature superconductor–edge metal–insulator transition in two-dimensional bosonic systems
(Peer reviewed; Journal article, 2022)Motivated by the recent experimental observation of an intermediate bosonic metallic state in the two-dimensional superconductor-insulator transition at T = 0 , we study an extended Bose-Hubbard model in the limit of a ...
