【摘要】 通过Dyson玻色子展开及修正的Jancovici和Schiff代换,得到费米子集体S,D对态空间与相互作用玻色子模型s,d空间之间的一一对应。费米子算符的玻色子像被唯一确定,IBM哈密顿量具有非厄米形式。费米子矩阵元能够在玻色子空间内直接计算,并且,当需要清除伪态时,相应的投影计算也能在玻色子空间进行。更多还原

【Abstract】 Through boson expansion and the modified Jancovici-Schiff substitution a 1-to-1 correspondence between fermion collective pair space and the interacting boson space is obtained. The boson mappings of fermion operators are uniquely determined and the IBM Hamiltonian takes a non-Hermitian form. The calculation of fermion matrix elements and spurious problem are also discussed.更多还原
