Topological changes of two-dimensional magnetic textures

Topological changes in a two-dimensional foam cluster.

Experiments on a small cluster of bubbles in a nominally two-dimensional foam show an instability in which a topological change forces one of the bubbles to be ejected to the outside of the cluster at a point where this is not predicted by a two-dimensional model of a foam. This is interpreted in terms of the energy of the initial and ejected states and of the finite liquid content of the exper...

Nonparametric Estimation and Simulation of Two-Dimensional Gaussian Image Textures

testing the existence of features occupying a relatively small number of pixels on a textured background. For most The work to be described is motivated by the need to simulate a variety of real–world image textures, all of which can be well real-world images, the probability theory underlying such approximated by stationary Gaussian random fields (SGRFs). a testing procedure appears to be intr...

Computational design of two- dimensional topological materials

The progress in science and technology is largely boosted by the continuous discovery of new materials. In recent years, the state-of-art first-principles computational approach has emerged as a vital tool to enable materials discovery by designing a priori unknown materials as well as unknown properties of existing materials that are subsequently confirmed by experiments. One notable example i...
