Komar守恒量的有效值及其应用

Effective Values of Komar Conserved Quantities and Their Applications

Sujoy Kumar Modak, Saurav Samanta

摘要:

本文计算了Kerr-Newman(KN)黑洞的有效Komar角动量。这个结果在黑洞事件视界内外的任何径向距离上都是有效的。然后用质量和角动量的有效值导出一个恒等式($K_{χ^μ}=2ST$),它把对应于零Killing矢量($χ^μ$)的Komar守恒荷($K_{χ^μ}$)与这个黑洞的热力学量联系起来。作为这个恒等式的一个应用,导出了这个黑洞的广义Smarr公式.这证明了上述恒等式是固有非局部广义Smarr公式的局部形式。

英文摘要:

We calculate the effective Komar angular momentum for the Kerr-Newman (KN) black hole. This result is valid at any radial distance on and outside the black hole event horizon. The effcetive values of mass and angular momentum are then used to derive an identity ($K_{χ^μ}=2ST$) which relates the Komar conserved charge ($K_{χ^μ}$) corresponding to the null Killing vector ($χ^μ$) with the thermodynamic quantities of this black hole. As an application of this identity the generalised Smarr formula for this black hole is derived. This establishes the fact that the above identity is a local form of the inherently non-local generalised Smarr formula.
