在任意n(≥ 3)维Brans-Dicke引力理论中,我们给出了一个存在幂函数势的精确渐近Lifshitz黑洞解。在这个解中,动力学指数z由Brans-Dicke参数ω和n确定,无穷远处的渐近Lifshitz条件要求z > 1,它对应于 − (n − 1)/(n − 2) ≤ ω < −n/(n − 1)。另一方面,爱因斯坦标量场的无鬼条件要求0 < z ≤ 2(n − 2)/(n − 3)。我们计算了黑洞溶液的霍金温度,并讨论了定义其热力学性质时遇到的问题和建议。文中还给出了麦克斯韦场荷电解的一般形式。
A bstractWe present an exact asymptotically Lifshitz black hole solution in Brans-Dicke theory of gravity in arbitrary n(≥ 3) dimensions in presence of a power-law potential. In this solution, the dynamical exponent z is determined in terms of the Brans-Dicke parameter ω and n. Asymptotic Lifshitz condition at infinity requires z > 1, which corresponds to − (n − 1)/(n − 2) ≤ ω < −n/(n − 1). On the other hand, the no-ghost condition for the scalar field in the Einstein frame requires 0 < z ≤ 2(n − 2)/(n − 3). We compute the Hawking temperature of the black hole solution and discuss the problems encountered and the proposals in defining its thermodynamic properties. A generalized solution charged under the Maxwell field is also presented.
