Magnetic Vortex Crystals in Frustrated Mott Insulator

Quantum fluctuations become particularly relevant in highly frustrated quantum magnets and can lead to new states of matter.We provide a simple and robust scenario for inducing magnetic vortex crystals in frustrated Mott insulators.By considering a quantum paramagnet that has a gapped spectrum with six-fold degenerate low-energy modes, we study the magnetic-field-induced condensation of these Bladder Health modes.We use a dilute gas approximation to demonstrate that a plethora Bruschetta of multi-Q condensates are stabilized for different combinations of exchange interactions.
This rich quantum phase diagram includes magnetic vortex crystals, which are further stabilized by symmetric exchange anisotropies.Because skyrmion and domain-wall crystals have already been predicted and experimentally observed, this novel vortex phase completes the picture of emergent crystals of topologically nontrivial spin configurations.
