Dirac Quantization Condition for Monopole in Noncommutative Space-Time

Masud Chaichian, Subir Ghosh, Miklos Langvik, Anca Tureanu

摘要:

由于在非常短的距离上时空的结构被认为可能由于非对易效应而被修改,并且随着狄拉克量子化条件(DQC)$μe = \frac{N}{2}\hbar c$探测磁场点奇点,一个自然的问题出现了,同样的条件是否仍然存在。我们表明,在一个非对易空间中的动态非对易量子力学模型的DQC保持相同的交换情况下,一阶的非对易参数$θ$,导致猜想,该条件不会改变更高的订单。

英文摘要:

Since the structure of space-time at very short distances is believed to get modified possibly due to noncommutativity effects and as the Dirac Quantization Condition (DQC), $μe = \frac{N}{2}\hbar c$, probes the magnetic field point singularity, a natural question arises whether the same condition will still survive. We show that the DQC on a noncommutative space in a model of dynamical noncommutative quantum mechanics remains the same as in the commutative case to first order in the noncommutativity parameter $θ$, leading to the conjecture that the condition will not alter in higher orders.
