AdS孤子是一个非奇异的时空，它具有一个平坦的共形边界和一个紧致的S1方向。我们发现了一个无水平cohomogeneity-1度量，描述了非线性引力振荡的AdS孤子在五个维度。我们称这种时空为共振AdS孤子。这个解决方案是作为非线性扩展的正常模式的AdS孤子双自旋-2胶球激发。共振AdS孤子的边界能动量张量具有时间周期分量，在对偶场理论中被解释为相干激发态。共振AdS孤子的物理量在固定的能量下是多值的，表明不同频率的解决方案之间的过渡。共振的AdS孤子的能量高于未变形的AdS孤子的能量，这与Horowitz和Myers提出的正能量猜想相一致。
The AdS soliton is a nonsingular spacetime that has a flat conformal boundary with a compact S 1 direction. We find a horizonless cohomogeneity-1 metric that describes nonlinear gravitational oscillations of the AdS soliton in five dimensions. We call this spacetime the resonating AdS soliton. This solution is obtained as the nonlinear extension of normal modes of the AdS soliton dual to spin-2 glueball excitations. The boundary energy momentum tensor of the resonating AdS soliton has time periodic components, and it is interpreted as a coherently excited state in the dual field theory. Physical quantities of the resonating AdS soliton are multivalued at a fixed energy, suggesting a transition between different frequency solutions. The energy of the resonating AdS soliton is higher than that of the undeformed AdS soliton, in accordance with the positive energy conjecture proposed by Horowitz and Myers.
