当D2-D0束缚态足够非极值时，它表现出Gregory-Laflamme不稳定性。如果没有D0-膜，则所需的非极值是有限的。当大多数极值质量来自D0膜时，所需的非极值很小。使用局部热力学分析来确定不稳定性阈值的位置，然后将其与线性化运动方程的数值分析进行比较。热力学分析揭示了非对易场理论在有限温度下的不稳定性，这种不稳定性可能只发生在非常长的波长，当接近去耦合极限时。
The D2-D0 bound state exhibits a Gregory-Laflamme instability when it is sufficiently non-extremal. If there are no D0-branes, the requisite non-extremality is finite. When most of the extremal mass comes from D0-branes, the requisite non-extremality is very small. The location of the threshold for the instability is determined using a local thermodynamic analysis which is then checked against a numerical analysis of the linearized equations of motion. The thermodynamic analysis reveals an instability of non-commutative field theory at finite temperature, which may occur only at very long wavelengths as the decoupling limit is approached.
