Researchers explain the distinctive low-temperature thermal properties of glasses using molecular dynamics simulations. By focusing on string-like defects, they were able to create a unified ...

The low-frequency vibrational and low-temperature thermal properties of amorphous solids are markedly different from those of crystalline solids. This situation is counterintuitive because all solid ...

Researchers have developed a new method for understanding the structure organization of disordered materials fundamentally different from previous geometric approaches of ordered crystals. This ...

image: Many substances with different chemical and physical properties, from diamonds to graphite, are made up of carbon atoms. Amorphous forms of solid carbon do not have a fixed crystal structure ...

Glassy states represent a fascinating class of disordered materials in which atoms or molecules are frozen into non-crystalline arrangements. Their vibrational properties differ markedly from those of ...

Anything made out of plastic or glass is known as an amorphous material. Unlike many materials that freeze into crystalline solids, the atoms and molecules in amorphous materials never stack together ...

In a crystalline solid, the atoms form an ordered lattice. Crystalline solids respond elastically to small deformations: When the applied strain is removed, the macroscopic stress, as well as the ...
