TL;DR: In this paper, the authors predict that van der Waals layered MnBi$_2$Te$_4$-family materials show two-dimensional (2D) ferromagnetism in the single layer and three-dimensional(3D) $A$-type antiferromagnetic topological insulator in the bulk.

TL;DR: In this article, the authors predict a series of van der Waals layered MnBi2Te4-related materials that show intralayer ferromagnetic and interlayer antiferromagnetic exchange interactions, including a topological axion state on the surface, a type II magnetic Weyl semimetal with one pair of Weyl points, as well as a collection of intrinsic axion insulators and quantum anomalous Hall (QAH) insulators in even and odd-layer films, respectively.

TL;DR: In this paper, the authors show how the Berry curvature of the collinear antiferromagnets can be engineered under external electric fields, uncovering the onset of a quantized anomalous Hall conductance with a high Chern number of three in a MnBi{}_{2}$Te${}_{4}$ thin film under a specific electric field.

TL;DR: In this article, the effective cluster interactions of O vacancies in cuprate superconductors are mapped out by combining first-principles total energy calculation with the automated structure inversion method.

TL;DR: In this paper, a combination of charge difference analysis, density of states projection, and constraint magnetization calculation is used to show that the H-doped electron is spontaneously trapped by a nonunique Co ion and is fully spin polarized by the onsite Hund's rule coupling.
