论文摘要
我们在存在自我相互作用的标量场的情况下研究爱因斯坦 - 欧拉 - 海森贝格理论，最小化与重力耦合。我们通过分析磁性磁盘的磁场方程，并获得了新颖的磁性毛茸茸的黑洞。标量场为黑洞带有次要标量头发。当Euler-Heisenberg参数和磁电荷较小时，毛茸茸的黑洞会发展三个视野，当标量电荷和重力质量较大时，地平线半径越大。物质的存在和黑洞地平线外的磁场仅适用于小黑洞的温度。计算热容量，我们表明的是，渐近广告Euler-Heisenberg毛茸茸的黑洞经历了二阶相变，然后稳定下来。同样，对于渐近广告Euler-Heisenberg毛茸茸的黑洞也违反了能量条件。
We study the Einstein-Euler-Heisenberg theory in the presence of a self interacting scalar field, minimally coupled to gravity. We solve analytically the field equations for the magnetically charged case and we obtain novel magnetically charged hairy black holes. The scalar field dresses the black hole with a secondary scalar hair. The hairy black hole develops three horizons when Euler-Heisenberg parameter and the magnetic charge are small and the horizon radius is getting large when the scalar charge and the gravitational mass are large. The presence of matter and the magnetic field outside the horizon of the black hole increases the temperature only for small black holes. Calculating the heat capacity we show that the asymptotically AdS Euler-Heisenberg hairy black hole undergoes a second order phase transition and then it is stabilized. Also the weak energy condition is violated for the asymptotically AdS Euler-Heisenberg hairy black hole.
