In this paper we consider holographic model of exciton condensation in double monolayer Dirac semimetal. Exciton is bound states of an electron and a hole. Being Bose particles, excitons can form a Bose—Einstein condensate. We study formation of two types of condensates. In first case both the electron and the hole forming the exciton are in the same layer (intralayer condensate), in the second case the electron and the hole are in different layers (interlayer condensate). We study how the condensates depend on the distance between layers and the mass of the quasiparticles in presence of a strong magnetic field. In order to take into account possible strong Coulomb interaction between electrons we use holographic appoach. The holographic model consists of two D5 branes embedded into anti de Sitter space. The condensates are described by geometric configuration of the branes. We show that the distance between layers at which interlayer condensate disappears decreases with quasiparticle mass.

在本文中，我们考虑了双层单层狄拉克半金属中激子凝聚的全息模型。激子是电子和空穴的束缚态。激子是Bose粒子，可以形成Bose-Einstein凝聚物。我们研究两种冷凝物的形成。在第一种情况下，电子和形成激子的空穴都在同一层中（层内冷凝物），在第二种情况下，电子和空穴在同一层中（层间冷凝物）。我们研究在强磁场存在下，冷凝物如何取决于层之间的距离和准粒子的质量。为了考虑电子之间可能存在的强库仑相互作用，我们使用全息方法。全息模型由嵌入反de Sitter空间的两个D5黄铜组成。冷凝物由黄铜的几何构型描述。我们表明，层间冷凝物消失的层之间的距离随准粒子质量而减小。
