洛伦兹破坏与黑洞热力学:康普顿散射过程

Lorentz violation and black-hole thermodynamics: Compton scattering process

E. Kant, F. R. Klinkhamer, M. Schreck

摘要:

考虑了一种洛伦兹非不变的量子电动力学修正,其中光子由修正的麦克斯韦理论的非双折射扇区描述,电子由标准的狄拉克理论描述.这些光子和电子在史瓦西时空背景中传播和相互作用。对于适当的洛伦兹破坏参数,光子有一个位于史瓦西视界之外的有效视界。一种特殊类型的康普顿散射事件,发生在这两个视界之间(在光子能区),并最终减少了黑洞的质量,被发现具有非零概率。这些事件可能允许违反广义热力学第二定律在洛伦兹非不变理论考虑。

英文摘要:

A Lorentz-noninvariant modification of quantum electrodynamics (QED) is considered, which has photons described by the nonbirefringent sector of modified Maxwell theory and electrons described by the standard Dirac theory. These photons and electrons are taken to propagate and interact in a Schwarzschild spacetime background. For appropriate Lorentz-violating parameters, the photons have an effective horizon lying outside the Schwarzschild horizon. A particular type of Compton scattering event, taking place between these two horizons (in the photonic ergoregion) and ultimately decreasing the mass of the black hole, is found to have a nonzero probability. These events perhaps allow for a violation of the generalized second law of thermodynamics in the Lorentz-noninvariant theory considered.
