Wannier states and spin supersolid physics in the triangular antiferromagnet KCo(SeO)
M. Zhu, Leandro M. Chinellato, V. Romerio +8
We combine ultra-high-resolution inelastic neutron scattering and quantum Monte Carlo simulations to study thermodynamics and spin excitations in the spin-supersolid phase of the t…

Large- SU(4) Schwinger boson theory for coupled-dimer antiferromagnets
Shang-Shun Zhang, Yasuyuki Kato, E. A. Ghioldi +3
We develop a systematic large- expansion based on the Schwinger boson representation of SU(4) coherent states of dimers for the paradigmatic spin- bilayer square lattice He…
