q变形量子力学中的动力学对称性
Dynamical Symmetries in q-deformed Quantum Mechanics
摘要:
构造了q变形谐振子的动力学代数。其结果是,我们发现的自由变形的哈密顿量以及作为一个复杂的,动量相关的相互作用的哈密顿量的变形振子通常的正则变量。进而构造了一个定义良好的代数SU $_q$(1,1),它具有一致的共轭性质和余乘性质.我们得到了这个代数的非最低权表示。
英文摘要:
The dynamical algebra of the q-deformed harmonic oscillator is constructed. As a result, we find the free deformed Hamiltonian as well as the Hamiltonian of the deformed oscillator as a complicated, momentum dependent interaction Hamiltonian in terms of the usual canonical variables. Furthermore we construct a well-defined algebra SU$_q$(1,1) with consistent conjugation properties and comultiplication. We obtain non lowest weight representations of this algebra.
