Properties of the skyrmion crystal SkX-2 in the Heisenberg triangular lattice with scalar chirality
H. Bocquet, C. J. Ganahl, M. Scheurer +2
Skyrmion crystals have been primarily discovered under a magnetic field for materials with non-centrosymmetric interactions. More recent developments have investigated the stabilit…
Nonperturbative Semiclassical Spin Dynamics for Ordered Quantum Magnets
Hao Zhang, Tianyue Huang, Allen O. Scheie +7
In ordered quantum magnets where interactions between elementary excitations dominate over their kinetic energy, perturbative approaches often fail, making non-perturbative methods…
Chiral Heisenberg Gross-Neveu-Yukawa criticality: Honeycomb vs. SLAC fermions
Thomas C. Lang, Andreas M. Läuchli
We perform large scale quantum Monte Carlo simulations of the Hubbard model at half filling with a single Dirac cone close to the critical point, which separates a Dirac semi-metal…
Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…
Universal dynamics of a pair condensate
Qing Huang, Hao Zhang, Yiqing Hao +10
Pair condensates appear in multiple branches of physics, always introducing exotic phenomena. The pair condensate in quantum magnetism is the spin nematic, whose static (quadrupola…
