利用3+1维黑洞与标量场耦合的引力对偶理论，研究了具有负宇宙常数的2+1维超导体模型。在有限的温度T和背景磁场B的存在下，我们使用数值和分析技术来解决完整的麦克斯韦标量运动方程的背景几何形状，找到非平凡的本地化的解决方案，对应于冷凝液滴，涡。这些解决方案的性质使我们能够推导出（B，T）相图的几个关键特征。
We study a 2+1 dimensional model of superconductors using a 3+1 dimensional gravitational dual theory of a black hole coupled to a scalar field, with negative cosmological constant. In the presence of finite temperature T and a background magnetic field B, we use numerical and analytic techniques to solve the full Maxwell-scalar equations of motion in the background geometry, finding non-trivial localized solutions that correspond to condensate droplets, and to vortices. The properties of these solutions enable us to deduce several key features of the (B,T) phase diagram.
