论文摘要
最近在ADS/CFT对应关系的背景下，最近提出了对黑洞背景中稳定大量颗粒的物理学的解释。有人认为，稳定轨道的存在表明双重状态不会在热时间尺度上进行热化，并且可以将大量激发解释为双场理论中的亚稳态。在这里，我们研究了爱因斯坦 - 洛维洛克理论中D维渐近抗DE保姆（ADS）黑洞的背景下的巨大颗粒的运动。我们表明，与渐近平坦的外壳不同，对于任何较高的曲率lovelock校正，在距黑洞距离处出现稳定的圆形轨道。我们发现远处圆形轨道和径向振荡频率的频率的一般分析表达式。我们表明，相应的校正具有与Schwarzschild-Ads案例中相同的功率，这意味着对于任何Lovelock理论来说，具有温度的通用缩放。
An interpretation to the physics of stable geodesics of massive particles in black hole backgrounds has been recently proposed in the context of the AdS/CFT correspondence. It was argued that the existence of stable orbits indicates that the dual state does not thermalize on a thermal time scale and the bulk excitations can be interpreted as metastable states in the dual field theory. Here we study motion of massive particles in the background of the D-dimensional asymptotically anti-de Sitter (AdS) black holes in the Einstein-Lovelock theory. We show that, unlike the asymptotically flat case, for any kind of higher curvature Lovelock corrections there appear a stable circular orbit at a distance from the black hole. We find the general analytical expressions for the frequencies of distant circular orbits and radial oscillation frequencies. We show that the corresponding correction has the same power as in the Schwarzschild-AdS case, implying a universal scaling with the temperature for any Lovelock theory.
