Anomalous continuum scattering and higher-order van Hove singularity in the strongly anisotropic S = 1/2 triangular lattice antiferromagnet
Pyeongjae Park, E. A. Ghioldi, Andrew F. May +10
The S = 1/2 triangular lattice antiferromagnet (TLAF) is a paradigmatic example of frustrated quantum magnetism. An ongoing challenge involves understanding the influence of exchan…

Quantum and classical spin dynamics across temperature scales in the S = 1/2 Heisenberg antiferromagnet
Pyeongjae Park, G. Sala, Daniel M. Pajerowski +6
Using the framework of semi-classical Landau-Lifshitz dynamics (LLD), we conduct a systematic investigation of the temperature-dependent spin dynamics in the S = 1/2 Heisenberg squ…
