Abstract
A method of obtaining the partition function for a system of electrons is developed by defining a new density matrix, in which the Fermi statistics is explicitly incorporated. The corresponding Bloch equation is formulated and a practical method of solving the equation is obtained for weak potential. This theory is applied to structurally disordered ststems which might be reasonable models for liquid metals.
Fermi통계를 도입한 새로운 밀도행렬을 정의함으로써 전자들의 Partition 함수를 구하는 방법이 마련되었다. 새 밀도행렬에 대응하는 Bloch방정식이 형성되었고 약한 Potential에 대하여 이것을 푸는 방법이 얻어겼다. 이 이론은 액체금속의 모델이 될 수 있는 구조적 불규칙계에 적용되었다.
