论文摘要
我们研究了核心孔孔中核心系统的行为（孔的宽度为颗粒的三个直径）。在先前的研究中，表明强限制的系统形成由几个三角形或方层组成的结晶相。这些阶段也可以视为FCC或HCP结构的切割。我们表明，核心软系统的行为更加复杂。我们还观察到一个准晶期。此外，具有两个三角形层的相位比具有两个正方形层的相位较低，这与之前研究的系统的行为形成鲜明对比。这些结果表明，强限制系统的相行为比以前更复杂。
We investigate a behavior of a core-softened system in a thin slit pore (the width of the pore is equil to three diameters of the particles). In previous studies it was shown that strongly confined systems form crystalline phases which consist of several triangular or square layers. These phases can be also considered as cuts of FCC or HCP structures. We show that the behavior of the core-softened system is more complex. We observe also a quasicrystalline phase. Moreover, the phase with two triangular layers appears at lower densities than the one with two square layers which is in contrast to the behavior of the systems studied before. These results demonstrate that the phase behavior of strongly confined systems can be even more complex than it was supposed before.
