Spontaneous magnetization of quantum XY-chain from finite chain form-factor
Description
Using the explicit factorized formulas for matrix elements (form-factors) of the spin operators between vectors of the Hamiltonian of a finite quantum XY-chain in a transverse field, the spontaneous magnetization for σx and σy is re-derived in a simple way.
