New class of topological crystalline insulators (TCI) have been proposed, but are yet to be experimentally evidenced. Here, the authors evidence two massless Dirac fermions protected by the combination of time-reversal symmetry T and Ĉ 2y on the (01

Topological side surface, characterization of a weak topological insulator (WTI), has rarely been investigated. Here, Zhang et al. visualize a quasi-one dimensional, spin-momentum locked band on the side surface of the WTI candidate ZrTe5, and manipu

Due to the lack of full rotational symmetry in condensed matter physics, solids exhibit new excitations beyond Dirac and Weyl fermions, of which the sixfold excitations have attracted considerable interest owing to the presence of maximum degeneracy

To understand the anomalous electronic transport properties of ZrTe5 remains an elusive puzzle. Here, Zhang et al. report direct electronic evidence to the origin of the resistivity anomaly and temperature induced Lifshitz transition in ZrTe5, indica

By means of first-principles calculations and crystal structure searching techniques, we predict that a different NaCaBi family crystallized into the ZrBeSi-type structure (i.e., P6_{3}/mmc) are strong topological insulators (STIs). Taking P6_{3}/mmc

Based on first-principles calculations and a symmetry-based indicator analysis, we find a class of topological crystalline insulators (TCIs) with a C_{2} rotation anomaly in a family of Zintl compounds, including Ba_{3}Cd_{2}As_{4}, Ba_{3}Zn_{2}As_{4

Charge neutrality and their expected itinerant nature makes excitons potential transmitters of information. However, exciton mobility remains inaccessible to traditional optical experiments that only create and detect excitons with negligible momentu
