Persistence of the Berezinskii-Kosterlitz-Thouless transition with long-range couplings

Luis Walther, Josef Willsher, Johannes Knolle

The Berezinskii-Kosterlitz-Thouless (BKT) transition is an archetypal example of a topological phase transition, which is driven by the proliferation of vortices. In this Letter, w…

Dynamics and stability of U(1) spin liquids beyond mean-field theory: Triangular-lattice $J_{1}$ - $J_{2}$ Heisenberg model

Josef Willsher, Johannes Knolle

Quantum spin liquids (QSLs) are long-range entangled phases of frustrated magnets exhibiting fractionalised spin excitations. In two dimensions, there is limited analytical underst…
