论文摘要
我们研究了全息巨大重力的Schwarzschild黑洞的时空产生的潮汐作用，由于大量的重力，它具有两个额外的质量参数。结果，我们已经获得了大量的重力影响潮汐力的角分量，而径向分量的形式与无质量重力的形式相同。另一方面，通过求解大地偏差方程，我们发现附近两个大地测量学的径向成分在掉入黑洞时不断拧紧，并且经过事件时，由于大量的重力而突然无限地伸展。但是，附近两个大地测量学的角度首先伸展，到达峰值，然后在掉入黑洞时被压缩。此外，我们还表明，由于固定重力质量的黑洞质量较小，角部成分更容易变形在出发位置附近。
We investigate tidal effects produced in the spacetime of Schwarzschild black hole in holographic massive gravity, which has two additional mass parameters due to massive gravitons. As a result, we have obtained that massive gravitons affect the angular component of the tidal force, while the radial component has the same form with the one in massless gravity. On the other hand, by solving the geodesic deviation equations, we have found that radial components of two nearby geodesics keep tightening while falling into the black hole and after passing the event horizons get abruptly infinitely stretched due to massive gravitons. However, angular components of two nearby geodesics get stretched firstly, reach a peak and then get compressed while falling into the black hole. Moreover, we have also shown that the angular components are more easily deformed near the departure position as the mass of a black hole is smaller for a fixed graviton mass.
