TL;DR: In this paper, the topological semimetal, a three-dimensional phase of a magnetic solid, is described and it may be realized in a class of pyrochlore iridates based on calculations using the LDA+U$ method.

TL;DR: This work presents an experimental and theoretical study of an active metamaterial—composed of coupled gyroscopes on a lattice—that breaks time-reversal symmetry and presents a mathematical model that explains how the edge mode chirality can be switched via controlled distortions of the underlying lattice.

TL;DR: In this article, a framework for classifying phases of one-dimensional interacting fermions was proposed, focusing on spinless Fermions with time-reversal symmetry and particle number parity conservation.

TL;DR: In this paper, the authors studied three-dimensional insulators with inversion symmetry in which other point group symmetries, such as time reversal, are generically absent, and showed that certain information about such materials' behavior is determined by just the eigenvalues under inversion symmetric of occupied states at time reversal invariant momenta (TRIM parities).

TL;DR: In this article, it was shown that whenever protected surface states exist, a corresponding protected ''mode'' exists in the entanglement spectrum as well, and that the spectrum sometimes succeeds better at indicating topological phases than surface states.
