论文摘要
这是对F. cinti和M. Boninsegni对我们最近在二维偶极系统中[R.Bombín，F。Mazzanti和J. Boronat，物理评论A 100，0636614（2019）中的评论回答。该评论中表达的对我们的工作的主要批评是，我们没有明确地向总超流体分数报告两个空间贡献。在这里，我们分析了对应于条纹相位的相位图的结果，靠近气体到条纹过渡线，以及低于BKT临界温度的温度。从空间顺序出现的方向上，对超流体分数的系统大小的缩放表明，它在热力学极限中仍然有限，正如我们在原始工作中已经指出的那样。这使我们能够声明条纹阶段在低温下是超氟。此外，我们提供了一些评论，有助于了解Cinti和Boninsegni和我们的结果之间的差异来自何处。
This is a Reply to the Comment from F. Cinti and M. Boninsegni on our recent work on the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a two-dimensional dipolar system [R.Bombín, F. Mazzanti and J. Boronat, Physical Review A 100, 063614 (2019)]. The main criticism about our work, expressed in that Comment, is that we did not explicitly report the two spatial contributions to the total superfluid fraction. Here, we analyze our results for a point of the phase diagram corresponding to the stripe phase, close to the gas to stripe transition line, and for a temperature below the BKT critical temperature. The scaling with the system size of the contribution to the superfluid fraction, coming from the direction in which spatial order appears, shows that it remains finite in the thermodynamic limit, as we already stated in our original work. This allow us to state that the stripe phase is superfluid at low temperatures. Furthermore, we offer some comments that help to understand where the differences between the results of Cinti and Boninsegni and ours comes from.
