Kerr-NUT-(A)dS时空中可积的弱电磁场

Weak electromagnetic field admitting integrability in Kerr-NUT-(A)dS spacetimes

Ivan Kolar, Pavel Krtous

摘要:

我们研究高维一般旋转黑洞时空的性质,即所谓的Kerr-NUT-(A)dS时空,以及具有相同显式和隐式对称性的相关空间族。在这些空间中,我们研究了弱电磁场存在下的粒子运动,并将其与其算子类比进行了比较。首先,我们找到了经典观测量和它们的算子对应物的一般交换性条件,然后我们研究了这些条件在Kerr-NUT-(A)dS和相关空间中的满足。我们发现弱电磁场的最一般形式与粒子运动的完全可积性和场算子的可商性相容。对于这样的场,我们用分离变量法求解了带电的Hamilton-Jacobi和Klein-Gordon方程。

英文摘要:

We investigate properties of higher-dimensional generally rotating black-hole spacetimes, so called Kerr-NUT-(A)dS spacetimes, as well as a family of related spaces which share the same explicit and hidden symmetries. In these spaces, we study a particle motion in the presence of a weak electromagnetic field and compare it with its operator analogies. First, we find general commutativity conditions for classical observables and for their operator counterparts, then we investigate a fulfillment of these conditions in the Kerr-NUT-(A)dS and related spaces. We find the most general form of the weak electromagnetic field compatible with the complete integrability of the particle motion and the comutativity of the field operators. For such a field we solve the charged Hamilton-Jacobi and Klein-Gordon equations by separation of variables.
