本文用全息方法研究了热化现象。解释在引力方面,我们考虑引力坍缩的薄壳的尘埃在时空主导的精粹暗能量。利用归一化测地线长度和最小面积曲面等热化探针,研究了经典暗能量态参量对热化的影响。结果表明,等离子体的状态参数越小,等离子体越难热化。我们还研究了热化速度和热化加速度。我们希望我们的研究结果可以揭示暗能量的本质。
In this paper, the thermalization has been studied holographically. Explicitly in the gravity side, we consider the gravitational collapse of a thin shell of dust in a spacetime dominated by quintessence dark energy. With the thermalization probes such as the normalized geodesic length and minimal area surface, we study the effect of the state parameter for the quintessence dark energy on the thermalization. Our results show that the smaller the state parameter of quintessence is, the harder the plasma to thermalize. We also investigate the thermalization velocity and thermalization acceleration. We hope our results here can shed light on the nature of the quintessence dark energy.
