H. Falomir, J. Gamboa, M. Loewe, F. Mendez, J. C. Rojas

摘要:

研究了相空间中自旋非对易的三维谐振子。该体系具有规则的辛结构,利用超对称量子力学方法,精确计算了体系的基态。我们发现这个态是无限简并的,并且具有明显的自发破缺对称性。通过对海森堡方程的分析,我们证明了总角动量守恒。

英文摘要:

A three-dimensional harmonic oscillator with spin non-commutativity in the phase space is considered. The system has a regular symplectic structure and by using supersymmetric quantum mechanics techniques, the ground state is calculated exactly. We find that this state is infinitely degenerate and it has explicit spontaneous broken symmetry. Analyzing the Heisenberg equations, we show that the total angular momentum is conserved.
