摘要: 引入厄米多项式算符并用其正规乘积展开式推导出了粒子数态|n)在坐标表象和动量表象下的波函数,并由此得出了坐标和动量本征态的福克(Fock)表示形式,这是一个简洁而全新的推导方法.

Abstract: By introducing the Hermite polynomial operator and deriving its normally ordered expansion, we derive the wave functions of particle number state in the coordinate representation and momentum representation, respectively, which can directly lead to the Fock representation of coordinate and momentum eigenstate. Our way is brand-new and concise.

Key words: Hermite polynomial operator: normal ordering expansion, particle number state, wave function
