The Energy-Spin Correlation Function of 2-D Ising Model With External Magnetic Field for T>T_c

Under the scaling limit, i.e. T→Tc+, H→O, R→∞, where h=const. H|T-Tc|-15/8 is fixed and small, while r=R|T-Tc|is fixed and large, we investigate the energy-spin correlation function <σM1, N1σM2, N2εN3, N3> of Ising model with small external magnetic field. By cluster expansion we obtai...

Zusammenfassung:Under the scaling limit, i.e. T→Tc+, H→O, R→∞, where h=const. H|T-Tc|-15/8 is fixed and small, while r=R|T-Tc|is fixed and large, we investigate the energy-spin correlation function <σM1, N1σM2, N2εN3, N3> of Ising model with small external magnetic field. By cluster expansion we obtain its leading and next leading terms related to K0（nr） and K1（nr） up to order h2.
