最近对吸附在石墨上的第二层的扭转振荡器测量已经确定了在第三层促进附近的覆盖范围内的异常超流响应，具有四个不同的覆盖范围。在这里，我们提出的超流响应的详细信息，在覆盖制度下立即低于第三层的促进。推断的超流分数的缩放分析显示，控制超流响应的特征温度降低，接近零的覆盖范围附近的模拟预测的第二层，形成一个传统的不相称的固体。
Recent torsional oscillator measurements on the second layer ofadsorbed on graphite have identified an anomalous superfluid response over a coverage range near third-layer promotion, with four distinct coverage regimes. Here, we present details of the superfluid response in the coverage regime immediately below third-layer promotion. A scaling analysis of the inferred superfluid fraction shows the characteristic temperature governing the superfluid response to decrease, approaching zero near the coverage at which simulations predict the second layer to form a conventional incommensurate solid.
