摘要

无序拓扑在非晶态固体的结构中引入了额外的自由度，主要增强了局部原子迁移率。与相应的晶体（即具有相同化学计量但具有有序结构的固体）相比，这导致了这些系统的物理性质的实质性和惊人的变化。在这篇文章中，考虑了玻璃的热力学和振动方面与拓扑无序之间的可能联系，强调了具有相同化学计量的结晶固体和无定形固体之间最显著的差异。

Effects of topological disorder on thermodynamic and vibrational properties of amorphous solids

The disordered topology introduces additional degrees of freedom in the structure of amorphous solids mainly enhancing the local atomic mobility. This gives rise to substantial and amazing changes of the physical properties of these systems compared to the corresponding crystals, i.e. solids having the same stoichiometry, but over an ordered structure. In this article, the possible connection between the thermodynamic and vibrational aspects of glasses and the topological disorder is considered, emphasizing the most significant differences between crystalline and amorphous solids having the same stoichiometry.

期刊介绍： This journal is of a multi- and inter-disciplinary nature and covers a broad range of fields including mathematics, computer science, physics, chemistry, biology, earth sciences, and their intersection. History of science is also included within the topics addressed by the journal. The transactions of the Pelorian Academy started out as periodic news sheets containing the notes presented by the members of the Divisions into which the Academy has been and still is organized, according to subject areas. The publication of these notes for the Division (“Classe”) of Mathematical, Physical and Natural Sciences is the responsibility of the Editorial Committee, which is composed of the Director of the division with the role of Chairman, the Vice-Director, the Secretary and two or more other members. Besides original research articles, the journal also accepts texts from conferences and invited talks held in the Academy. These contributions are published in a different section of the journal. In addition to the regular issues, single monographic supplements are occasionally published which assemble reports and communications presented at congresses, symposia, seminars, study meetings and other scientific events organized by the Academy or under its patronage. Since 2004 these transactions have been published online in the form of an open access electronic journal.
