Evidence of the Berezinskii-Kosterlitz-Thouless Phase in a Frustrated Magnet
Ze Hu, Zhen Ma, Yuan-Da Liao +10
The Berezinskii-Kosterlitz-Thouless (BKT) mechanism, building upon proliferation of topological defects in 2D systems, is the first example of phase transition beyond the Landau-Gi…

Kosterlitz-Thouless Melting of Magnetic Order in the Triangular Quantum Ising Material TmMgGaO
Han Li, Yuan Da Liao, Bin-Bin Chen +5
Frustrated magnets host the promises of material realizations of new paradigm of quantum matter, while direct comparison of unbiased model calculations with experimental measuremen…

Topological states from topological crystals
Zhida Song, Sheng-Jie Huang, Yang Qi +2
We present a scheme to explicitly construct and classify general topological states jointly protected by an onsite symmetry group and a spatial symmetry group. We show that all the…
