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…
Notes on Worldsheet-Like Variables for Cluster Configuration Spaces
Song He, Yihong Wang, Yong Zhang +1
We continue the exploration of various appearances of cluster algebras in scattering amplitudes and related topics in physics. The cluster configuration spaces generalize the famil…
Improved existence for the characteristic initial value problem with the conformal Einstein field equations
David Hilditch, Juan A. Valiente Kroon, Peng Zhao
We adapt Luk's analysis of the characteristic initial value problem in General Relativity to the asymptotic characteristic problem for the conformal Einstein field equations to dem…
Revisiting the characteristic initial value problem for the vacuum Einstein field equations
David Hilditch, Juan A. Valiente Kroon, Peng Zhao
Using the Newman-Penrose formalism we study the characteristic initial value problem in vacuum General Relativity. We work in a gauge suggested by Stewart, and following the strate…
Partition Functions of Gauge Theories on and Duality
Taro Kimura, Jun Nian, Peng Zhao
We compute the partition functions of gauge theories on using supersymmetric localization. The path integral reduces to a su…
