Title: Drinfeld twists (F-matrices) and symmetric Bethe vectors of  supersymmetric fermion models

Abstract:
 
A major open problem in quantum integrable systems is to get explicit and manageable expressions of their correlation

functions. There are two mainstream approaches for the computation of correlation functions: vertex operator method and Bethe ansatz

method. The former is based on a hypothesis while the latter has to deal with complicated combinatorial problems. Recent progress 

by Maillet et. al. and Flume et. al. has made the latter approach feasible for the computation of correlation functions and form factors.



Together with Wen-Li Yang and Shao-You Zhao, I have made advances in generalizing the approach to supersymmetric

fermion models. In this talk, I will show how Drinfeld twists or factoring F-matrices may help one to achieve the ultimate goal of 

constructing quantum correlators. I will briefly review what we have done so far.
 
All interested are invited to attend.
