The holon spectral function at finite temperature for high Tc superconductors

Abstract

Using the finite temperature Green's function method, the holon spectral function is calculated from the first order holon self-energy term. The interaction in the S-matrix expansion is the spin polaron Hamiltonian that allows us to analytically determine the holon self-energy term for multiple spin-wave processes. The usual prescription of analytic continuation enables us to obtain the retarded expression from the Matsubara self-energy term.
