初等3-费米子2-体算符的谱分解

Spectral decomposition of an elementary 3-fermion 2-body operator

Hubert Grudzinski, Jacek Hirsch

摘要:

在有限维三粒子反对称Hilbert空间上,求出了初等三费米子二体算符$3P^2_g\wedge I^1\equiv A^3 \sum\limits_{1\leq i < j \leq 3} P^2_g(i,j)A^3$的本征值和本征函数,其中$P^2_g$表示在二粒子反对称函数$g^2$上的投影算符,$A^3$表示三粒子反对称化算符.关键词:算符谱分解,费米子2-体算符

英文摘要:

The eigenvalues and eigenfunctions of an elementary 3-fermion 2-body operator $3P^2_g\wedge I^1\equiv A^3 \sum\limits_{1\leq i < j \leq 3} P^2_g(i,j)A^3$ acting on a 3-particle antisymmetric finite dimensional Hilbert space have been found. Here $P^2_g$ denotes the projection operator onto a 2-particle antisymmetric function $g^2$, while $A^3$ denotes the 3-particle antisymmetrizing operator. keywords: spectral decomposition of operators, fermion 2--body operators
