时空非对易性对Zitterbewegung的影响
Effect of Noncommutativity of Space-time on Zitterbewegung
摘要:
在本文中,我们提出了我们的调查结果的修改Zitterbewegung由于时空的非对易性。首先,我们研究时空的$κ$形变对Zitterbewegung的影响。为此,我们从$κ$ -变形狄拉克理论开始,并使用变形参数$a$中有效到一阶的$κ$ -变形狄拉克方程,我们发现Zitterbewegung中的修改在变形参数$a$中有效到一阶。在极限$a\rightarrow 0$中,我们得到了交换结果.其次,我们发现了双狭义相对论(DSR)的Magueijo-Smolin(MS)方法对Zitterbewegung的修正,并在极限$E_p \rightarrow \infty$下得到了对易时空中的结果。
英文摘要:
In this paper, we present the results of our investigation on the modification of Zitterbewegung due to the noncommutativity of the space-time. First, we study the effect of $κ$-deformation of the space-time on Zitterbewegung. For this, we start with the $κ$-deformed Dirac theory and using $κ$-deformed Dirac equation valid upto first order in deformation parameter $a$, we find the modification in the Zitterbewegung valid upto first order in the deformation parameter $a$. In the limit $a\rightarrow 0$, we get back the commutative result. Secondly, we find the modification in the Zitterbewegung due to the Magueijo-Smolin(MS) approach of doubly special relativity(DSR) and in the limit $E_p \rightarrow \infty$, we get back the result in the commutative space-time.
