Renormalized Classical Theory of Quantum Magnets
David Dahlbom, Hao Zhang, Zoha Laraib +3
We derive a renormalized classical spin (RCS) theory for quantum magnets by constraining a generalized classical theory that includes all multipolar fluctuations to a red…
Tetrahedral triple-Q magnetic ordering and large spontaneous Hall conductivity in the metallic triangular antiferromagnet Co1/3TaS2
Pyeongjae Park, Woonghee Cho, Chaebin Kim +14
The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is t…
Cubic Double Perovskites Host Noncoplanar Spin Textures
Joseph A. M. Paddison, Hao Zhang, Jiaqiang Yan +8
Magnetic materials with noncoplanar magnetic structures can show unusual physical properties driven by nontrivial topology. Topologically-active states are often multi-q structures…
A flexible class of exact Hubbard-Stratonovich transformations
Seher Karakuzu, Benjamin Cohen-Stead, Cristian D. Batista +2
We consider a class of Hubbard-Stratonovich transformations suitable for treating Hubbard interactions in the context of quantum Monte Carlo simulations. A tunable parameter al…
Field-induced spin level crossings within a quasi-XY antiferromagnetic state in BaFeSiO
Minseong Lee, Rico Schoenemann, Hao Zhang +11
We present a high-field study of the strongly anisotropic easy-plane square lattice = 2 quantum magnet BaFeSiO. This compound is a rare high-spin antiferromag…
BCS-BEC Crossover of Triplet Exciton Condensation in Bilayer Systems
Hidemaro Suwa, Shang-Shun Zhang, Cristian D. Batista
We study the BCS-BEC crossover phenomenon of triplet exciton condensation using a half-filled bilayer Hubbard model. We calculate the dynamical spin structure factor and the excito…
