相分离态的存在是具有热一级相变的无限体积系统的基本特征。在相变发生的能量之间，平衡均匀态要么是亚稳态，要么是失稳的。在这个范围内的稳定状态是不均匀的，相分离的状态。我们使用全息术来研究如何在有限体积的强耦合，四维规范理论，这张照片是修改。我们在平面极限N→∞中工作，这确保我们保持在热力学极限中。我们发现了一组丰富的非均匀状态的双亮度黑膜的引力侧，以及它们之间的第一和第二阶相变。我们建立了他们的本地（在）稳定性，并表明，完全非线性时间演化的大部分不稳定状态稳定的。
The existence of phase-separated states is an essential feature of infinite-volume systems with a thermal, first-order phase transition. At energies between those at which the phase transition takes place, equilibrium homogeneous states are either metastable or suffer from a spinodal instability. In this range the stable states are inhomogeneous, phase-separated states. We use holography to investigate how this picture is modified at finite volume in a strongly coupled, four-dimensional gauge theory. We work in the planar limit, N→∞, which ensures that we remain in the thermodynamic limit. We uncover a rich set of inhomogeneous states dual to lumpy black branes on the gravity side, as well as first-and second-order phase transitions between them. We establish their local (in) stability properties and show that fully non-linear time evolution in the bulk takes unstable states to stable ones.
