利用全息对偶性，我们研究了有限温度对四重量子化涡旋的不稳定性和分裂模式的影响，在这方面提供了有史以来第一次的分析。通过线性稳定性分析，我们揭示了两个连续的动力学转变的发生。在特定的低温下，主要的不稳定模式从二重旋转对称模式转变为三重旋转对称模式，然后在较高的温度下从三重旋转对称模式转变为四重旋转对称模式。随着温度的升高，我们还观察到五次和六次旋转对称不稳定模相继被激发。采用全非线性数值模拟，我们进一步证明，这两个新的动力学转变沿着温度诱导的不稳定性的五次和六次旋转对称模式，可以通过检查所产生的不同的分裂模式，这提供了一个有前途的路线，在冷原子气体的实验验证。
Using holographic duality, we investigate the impact of finite temperature on the instability and splitting patterns of quadruply quantized vortices, providing the first-ever analysis in this context. Through linear stability analysis, we reveal the occurrence of two consecutive dynamical transitions. At a specific low temperature, the dominant unstable mode transitions from the twofold rotational symmetry mode to the threefold one, followed by a transition from the threefold one to the fourfold one at a higher temperature. As the temperature is increased, we also observe the fivefold and sixfold rotational symmetry unstable modes get excited successively. Employing the full nonlinear numerical simulations, we further demonstrate that these two novel dynamical transitions, along with the temperature-induced instabilities for the fivefold and sixfold rotational symmetry modes, can be identified by examining the resulting distinct splitting patterns, which offers a promising route for the experimental verification in the cold atom gases.
