Am. Tikofsky et Rb. Laughlin, RESPONSE FUNCTION OF THE T-J MODEL CALCULATED USING ANYON TECHNIQUES, Physical review. B, Condensed matter, 50(14), 1994, pp. 10165-10189
We have computed zero-temperature properties of the t-J Hamiltonian us
ing the formalism of anyon superconductivity. The results of these cal
culations agree quantitatively with exact-diagonalization studies. The
se properties include the optical conductivity, the ground-state kinet
ic energy, and the ground-state magnetic energy. Implicit in this calc
ulational procedure is a Kosterlitz-Thouless transition temperature fo
r the onset of superconductivity.
