Topological terms of (2+ 1) d flag-manifold sigma models

R Kobayashi, Y Lee, K Shiozaki, Y Tanizaki - Journal of High Energy …, 2021 - Springer
A bstract We examine topological terms of (2+ 1) d sigma models and their consequences in
the light of classifications of invertible quantum field theories utilizing bordism groups. In …

SU (3) trimer resonating-valence-bond state on the square lattice

XY Dong, JY Chen, HH Tu - Physical Review B, 2018 - APS
We propose and study an SU (3) trimer resonating-valence-bond (tRVB) state with C 4 v
point-group symmetry on the square lattice. By devising a projected entangled-pair state …

Sigma-model analysis of SU (3) antiferromagnetic spins on the triangular lattice

I Takahashi, Y Tanizaki - Physical Review B, 2021 - APS
Using field-theoretic techniques, we study the SU (3) analog of antiferromagnetic
Heisenberg spin model on the triangular lattice putting the p-box symmetric representation …
