在Berenstein-Maldacena-Nastase（BMN）矩阵模型下研究了巨引力子的热不稳定性。我们分别计算了平凡真空和巨引力子周围量子涨落的单圈热修正。从自由能的精确公式可以看出，巨引力子在低温下是不稳定的，会分解成真空涨落。然而，在足够高的温度下，微小的真空涨落将凝聚形成巨引力子组态。计算中确定了巨引力子的转变温度。
The thermal instability of the giant graviton is investigated within the Berenstein-Maldacena-Nastase (BMN) matrix model. We calculate the one-loop thermal correction of the quantum fluctuation around the trivial vacuum and giant graviton, respectively. From the exact formula of the free energy we see that at low temperature the giant graviton is unstable and will dissolve into vacuum fluctuations. However, at sufficiently high temperature the trivial vacuum fluctuation will condense to form the giant graviton configuration. The transition temperature of the giant graviton is determined in our calculation.
