All crystals form as a result of two processes, called "nucleation" and "crystal growth," in a "supersaturated" liquid solution (a liquid with something dissolved in it; for example, salt). This will occur in a cave if it is flooded with one of these liquid solutions for as long as a...
How do crystals form and grow in glass-forming liquids: Ostwald's rule of stages and beyond. Int. J. Appl. Glass Sci. 1, 16-26.Schmelzer J W P, Fokin V M, Abyzov A S, Zanotto E D and Gutzow I 2010 How do crystals form and grow in glass-forming liquids: Ostwald's rule of...
Why Do Some Crystals Grow in Filamentary Shapes?It is now necessary to turn from "metal deposition" studies—the study of the mechanism by which ions move from the solution to the growth sites on the metal surface—and study the growth itself. This is a more complex task and it is ...

We stress that, while for crystals the classification of normal modes by their wavevectors reflects a physical symmetry of the systems, in glasses it is simply an artifact due to the use of PBCs. When large enough models are used to describe the glass, it is common practice to just sample...
We address the research question: What characterises student teachers' learning outcomes in various teacher education courses that emphasise arts-based teaching and learning? To be clear, we do not strive for characteristics that fit a traditional view on learning outcomes, often associated with input...
an effective quadratic potential, as expected, justifying the fit in Fig.3d. Note that the swimmers move at a fixed distance in the comoving frame, and that our model does not indicate what the collective speed is. A more detailed calculation based on Faxén’s first law can additionally ...
What Are Clouds? A Cloud is made of water drops or ice crystals floating (漂浮) in the sky. There are many kinds of cloud. Clouds are of great importance to Earth’s weather. The sky can be full of water. But most of the time you can’t see the water. The drops of water are ...
While these considerations are model and parameters dependent, and it is ultimately up to numerics to find the bistable and the DTC phases, what is universal and far reaching here is the concept that long-ranged DP, and PCA more generally, can host novel dynamical phases, such as DTCs. As...
As for the two-anyon system, quantum statistics could induce effective defects at two corners in the mapped 2D lattice, which could trap two anyons to form anyonic BICs. Moreover, we can also understand this phenomenon from a mathematical viewpoint. Following the analytical method by assuming a...
