摘要翻译：
用量子蒙特卡罗模拟方法研究了低温下预镀单原子层氪的石墨衬底上邻位氘和对位氢薄膜的吸附。我们的模型明确地包含了衬底波纹。计算了这些吸附膜在氢覆盖范围内的能量和结构特性。热力学稳定的吸附膜是固体，没有任何类似液体相的明确证据。在该体系中，邻位氘和对位氢的量子交换基本上是不存在的，直到零温度；因此，该系统在此极限下没有表现出超流性。我们的模拟提供了低温下畴壁流体稳定的证据，与最近的实验观察一致。

英文摘要：
  Adsorption of ortho-deuterium and para-hydrogen films on a graphite substrate, pre-plated with a single atomic layer of krypton, is studied theoretically by means of quantum Monte Carlo simulations at low temperature. Our model explicitly includes substrate corrugation. Energetic and structural properties of these adsorbed films are computed for a range of hydrogen coverages. Thermodynamically stable adsorbed films are solid, with no clear evidence of any liquid-like phase. Quantum exchanges of ortho-deuterium and para-hydrogen are essentially absent in this system, down to zero temperature; consequently, this system displays no superfluidity in this limit. Our simulations provide evidence of a stable domain wall fluid at low temperature, consistently with recent experimental observations.
