摘要
本文采用泛函积分方法研究了高温超导中玻色-费米子模型的长波激发.推导了能隙方程和激发谱方程,并且计算了在长波近似下费米场的玻色能谱,得到了简并和非简并激发模.
In this paper, longwave excitations in the bosonfermion model of high temperature superconductivity are investigated by means of functional integration method. The equations of energy gap and excitation spectrum are derived. Moreover, the Bose energy spectrums of Fermi fields are calculated under longwave approximation, the degenerate and nondegenerate excitation modes are obtained.
