Two dimensional vortex structures with multi scale interactions in thin film superconductors
摘要:
多尺度相互作用势可以有效地近似许多系统中粒子的相互作用。这种电位被广泛用于研究胶体体系、胶体-聚合物混合物、复杂液体(如水)和其他体系。此外,它是特别感兴趣的是,有效的相互作用的涡旋在一个薄的超导薄膜可以近似的多尺度潜力。本论文的主题就是这样一个系统。基于多尺度势,我们已经表明,该系统表现出大量的不同的阶段。特别重要的是,我们分析了系统性质的长程相互作用的影响,并表明,适当考虑长程作用力会导致系统相图的急剧变化。
英文摘要:
Interaction of particles of many systems can be effectively approximated by multiscale interaction potentials. Such potentials are widely used for investigation of colloidal systems and colloid-polymer mixtures, complex liquids (for instance, water) and other system. Also, it is of particular interest that effective interaction of vortices in a thin superconducting film can be approximated by a multiscale potential. The subject matter of the present paper is a system like this. Based on a multiscale potential we have shown that this system demonstrated a large number of different phases. It is particularly important that we analyze the influence of a long-range interaction of the system properties and show that properly taking into account long-range forces results in a dramatic change in the system phase diagram.
