Temperature- and field-dependent 1H-, 19F-, and 79,81Br-NMR measurements together with zero - field 79,81Br-NQR measurements on polycrystalline samples of barlowite, Cu4(OH)6FBr are conducted to study the magnetism and possible structural distortions on a microscopic level. The temperature dependence of the 79,81Br-NMR spin-lattice relaxation rates 1/T1 indicate a phase transition at TN $$\simeq$$≃ 15 K which is of magnetic origin, but with an unusually weak slowing down of fluctuations below…

Employing large-scale quantum Monte Carlo simulation and stochastic analytic continuation, the extended XXZ model on the kagome lattice is investigated, and it is found that, across the phase transitions from Z_{2} QSLs to different symmetry breaking phases, spin spectral functions can reveal the presence and condensation of emergent anyonic spinon and vison excitations.
