Bethe-State Counting and the Witten Index
Hongfei Shu, Peng Zhao, Rui-Dong Zhu +1
We count the Bethe states of quantum integrable models with twisted boundary conditions using the Witten index of 2d supersymmetric gauge theories. For multi-component models solva…

Remarks on 2d Unframed Quiver Gauge Theories
Peng Zhao, Hao Zou
We study 2d quiver gauge theories without flavor nodes. There is a special class of quivers whose gauge group ranks stay positive in any duality frame. We illus…
