在本文中,我们将协变相空间形式中与依赖于场的向量共轭的形式推广到包含内部规范变换的情形,当存在规范场时。在我们的形式中,对称生成元是微分同胚与内部规范变换的组合,并依赖于场构型。当在协变相空间形式中考虑对称生成元的场依赖性时,黑洞热力学第一定律成为一般不变引力理论的直接结果。为了验证我们形式的有效性,我们研究了爱因斯坦-麦克斯韦理论中环状黑洞以及爱因斯坦-欧拉-海森堡非线性电动力学中带电荷的爱因斯坦-欧拉-海森堡反德西特黑洞的守恒荷和热力学第一定律。
英文摘要
In this paper, we generalize the covariant phase space formalism conjugate to field dependent vectors to include internal gauge transformations when gauge fields are present. In our formalism, the symmetry generators are combination of diffeomorphisms plus internal gauge transformations and depend on the field configuration. When the field dependence of the symmetry generators is considered in the covariant phase space formalism, the first law of black hole thermodynamics is a direct result for generally invariant gravitational theories. To check the validity of our formalism, we investigate the conserved charges and the first laws of thermodynamics for a torus-like black hole in Einstein-Maxwell theory and a charged Einstein-Euler-Heisenberg AdS black hole in Einstein-Euler-Heisenberg nonlinear electrodynamics.
