将自旋引入经典相空间

Introducing spin to classical phase space

J. Leon, J. M. Martin

摘要:

自旋粒子的运动自由度进行了分析,并提出了一个明确的相空间和简单的结构,容纳他们的建设。利用旋量变量给出了经典自旋粒子的Poincare不变量理论,将Proca和Barut的工作推广到任意自旋。第二,量子化自然地与zitterbewegung的非物质性质有关。位置变量不能以正则方式从自旋中解脱出来,相空间也不能简化为通常的描述$(x,p)$和矢量自旋。Pacs:03.20.+ i,03.65.Sq,03.30.+ p,11.30.Cp

英文摘要:

The kinematic degrees of freedom of spinning particles are analyzed and an explicit construction of the phase space and the simplectic structure that accomodates them is presented. A Poincare invariant theory of classical spinning particles that generalizes the work of Proca and Barut to arbitrary spin is given using spinor variables. Second quantization is naturally connected to the unphysical nature of zitterbewegung. Position variables can not be disentangled from spin in a canonical way, nor can the phase space be reduced to the usual description $(x,p)$ and a vector spin. Pacs: 03.20.+i, 03.65.Sq, 03.30.+p, 11.30.Cp
