Stationary measures for higher spin vertex models on a strip
Zongrui Yang
We introduce a higher spin vertex model on a strip with fused vertex weights. This model can be regarded as a generalization of both the unfused six-vertex model on a strip arXiv:2…

Stationary measures for integrable polymers on a strip
Guillaume Barraquand, Ivan Corwin, Zongrui Yang
We prove that the stationary measures for the free-energy increment process for the geometric last passage percolation (LPP) and log-gamma polymer model on a diagonal strip is give…
