| 英文摘要 | The Green's function for a hole moving in an antiferromagnet is derived analytically in the long-wavelength limit. We find that the infrared divergence is eliminated in two and higher dimensions so that the quasiparticle weight is finite. Our results also suggest that the hole motion is polaronic in nature with a bandwidth proportional to t(2)/J exp[-c(t/J)(2)] (c is a constant) for J/t greater than or equal to 0.5. The connection of the long-wavelength approximation to the first-order approximation in the cumulant expansion is also clarified. |
