The hidden symmetry for a quantum system with an infinitely deep square-well potential

摘要

An infinitely deep square-well potential is studied by an SU(11,) algebra, not by an SO(2) algebra. The creation and annihilation operators for the system are obtained from the factorization method. Closed analytical expressions for the matrix elements of some relevant functions are evaluated. (C) 2002 American Association of Physics Teachers. [References: 12]
