洛伦兹净化

Depurification by Lorentz boosts

P. Kosinski, P. Maslanka

摘要:

我们考虑一个自旋为半整数的粒子,它在静止坐标系中是非相对论性的。假设粒子沿第三轴完全极化,我们计算运动观察者看到的布洛赫矢量。它的长度的结果表示在一些向量算子的色散线性动量。讨论了与局部化性质的关系。

英文摘要:

We consider a particle of half-integer spin which is nonrelativistic in the rest frame. Assuming the particle is completely polarized along third axis we calculate the Bloch vector as seen by a moving observer. The result for its length is expressed in terms of dispersion of some vector operator linear in momentum. The relation with the localization properties is discussed.
