论文摘要
我们提出了一种新的玻色子扩展理论，该理论没有先到封闭的代数近似值，这对于直到现在，这是必不可少的，作为传统实用的玻色子扩展方法的扩展，该方法的扩展是阐明核心集体运动的常规实用玻色子扩展方法，这是一种试图允许使用封闭式近似值的方法，即不适合使用ossos，可以使用boss，并允许使用boson，bossoss and bossoss bossons bossons booss osson booson seploson boson seploson booson seploson。比传统的实用方法更忠实地进入玻色子子空间。详细研究了由所有声子激发模式组成的两声器标准矩阵，该矩阵详细研究了我们应该如何构建fermion子空间的机制，这对于玻色子膨胀方法至关重要。常规的实用玻色子扩展方法已不当地应用了封闭的代数近似来增强保利原理的效果，应由那些不使用该近似值或正确使用的闭合近似值代替。
We propose a new boson expansion theory that does not premise the closed-algebra approximation, indispensable for formulation until now, as an extension of the conventional practical boson expansion methods that have tried to elucidate nuclear collective motion, which is a method that allows the closed-algebra approximation not to be used or to be used appropriately, enables us to obtain the boson expansion easier, and reproduces the fermion subspace onto the boson subspace more faithfully than the conventional practical methods. The two-phonon norm matrix composed of all the phonon excitation modes is investigated in detail, which reveals the mechanism, essential for the boson expansion methods, of how we should construct the fermion subspace to be mapped from the whole fermion space. The conventional practical boson expansion methods have applied the closed-algebra approximation improperly to strengthen the effect of the Pauli principle inappropriately, which should be replaced by those that do not use that approximation or use it properly.
