The ground state-vector of the $XY$ Heisenberg chain and the Gauss decomposition
N. Bogoliubov, C. Malyshev St. Petersburg Department of Steklov Institute of Mathematics, RAS Fontanka 27, St. Petersburg, Russia
Abstract:
The $XY$ Heisenberg spin$\frac12$ chain is considered in the fermion representation. The construction of the ground state-vector is based on the group-theoretical approach. The exact expression for the ground state-vector will allow to study the combinatorics of the correlation functions of the model.
Key words and phrases:
$XY$ Heisenberg spin chain, ground state-vector, Gauss decomposition.
