论文摘要
我们预测新的2D材料的角度依赖性超流体 - 过渡金属三卡构基化金（TMTC）。在TMTC Van der Waals异质结构（VDWH）中，间接激子的平均场进近进近流体中。我们使用不同的电势进行带电的载体相互作用来分析筛选对所研究现象的影响。我们的研究证明了TMTC VDWH中的角度依赖性超流体温度：对于给定密度，最大和最小的$ t_c $超流体沿链沿链和$ a $ a-directions发生。这项工作可以指导实现TMTC VDWH中各向异性超流体的实验研究。我们建议在TMTC VDWH中观察各向异性超流体的实验。
We predict angle-dependent superfluidity for a new class of 2D materials -- transition metals trichalcogenides (TMTC). Within a mean-field approach superfluidity of indirect excitons in TMTC van der Waals heterostructures (vdWHs) is studied. We use different potentials for charged carriers interaction to analyze the influence of the screening on the studied phenomena. Our study demonstrates the angle-dependent superfluidity temperature in TMTC vdWHs: for a given density a maximum and minimum $T_c$ of superfluidity occurs along chain and $a$-directions, respectively. This work can guide experimental research toward the realization of anisotropic superfluidity in TMTC vdWH. We suggest an experiment for the observation of anisotropic superfluidity in TMTC vdWH.
