$C_λ$扩展振子的谱生成代数和相干态

Spectrum generating algebra and coherent states of the $C_λ$-extended oscillator

C. Quesne

摘要:

$C_λ$ -扩展振子代数是Calogero-Vasiliev代数的推广,其中$C_λ$是$λ$阶的循环群,最近在超对称量子力学及其某些变体的上下文中被证明是非常有用的.这里我们确定了$C_λ$扩展振子的谱生成代数。然后我们构造了它的相干态,研究了它们的非经典性质,并将后者与作为特例得到的标准$λ$ -光子相干态进行了比较。最后,我们简要地回顾了与$C_λ$扩展振子相关的其他类型的相干态。

英文摘要:

$C_λ$-extended oscillator algebras, generalizing the Calogero-Vasiliev algebra, where $C_λ$ is the cyclic group of order $λ$, have recently proved very useful in the context of supersymmetric quantum mechanics and some of its variants. Here we determine the spectrum generating algebra of the $C_λ$-extended oscillator. We then construct its coherent states, study their nonclassical properties, and compare the latter with those of standard $λ$-photon coherent states, which are obtained as a special case. Finally, we briefly review some other types of coherent states associated with the $C_λ$-extended oscillator.
