Toda Darboux transformations and vacuum expectation values

Chengwei Wang, Mengyao Chen, Jipeng Cheng

Determinant formulas for vacuum expectation values $⟨s+k+n-m,-s|e^{H(\mathbf{t})}{\beta }_m^{\ast }\cdots {\beta }_1^{\ast }{\beta }_n\cdots {\beta }_{1}g|k⟩$ are given by using Toda Darboux transformations…
