Spontaneous Magnetization of Quantum XY-chain from Finite Chain Form-factors
Using the explicit factorized formulas for matrix elements (formfactors) of the spin operators between the eigenvectors of the Hamiltonian of a finite quantum XY-chain in a transverse field, the spontaneous magnetization for σ^x and σ^y is re-derived in a simple way.
