摘要：
We consider the XY Heisenberg spin 12 chain in the fermion representation. The construction of the ground-state vector is based on the group-theoretical approach. An exact expression for the ground-state vector will allow one to study the combinatorics of the correlation functions of the model. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
