| 摘 要： | 对于由4个费米子相互作用系统组成的哈密顿量的平均场理论,当只有S波超导时,由SU(2)(局域同构于SO(3))代数表达,P波超导可以通过SO(5)表达,而对于S-P混合波超导的情况则由SU(4)(局域同构于SO(6))代数表达.本文通过在SO(6)代数中引入了反映S波和P波混合超导的SO (4)子集,从而可以通过对相干...

| Abstract: | It has been well established that the mean field theory of the Hamiltonian for 4 fermions interaction system turns out to be expressed in terms of SU(2)(locally SO(3)) algebra for S-wave superconductivity,and SO(5) for P-wave superconductivity,whereas for the S-P wave mixture superconductivity is described by SU(4)(locally SO(6)) algebra.The P-wave superconductivity theories and their applications to liquid 3He have intensively been studied in many early publications,which lead to a significant progress in ... |
