Pressure-induced topological phase transition in noncentrosymmetric elemental tellurium.

Article Synopsis
- Recent advances in electronic band topology suggest a need to reevaluate the band structures of familiar materials, including elemental substances.
- Researchers have identified signs of a transition from a semiconductor to a Weyl semimetal in elemental tellurium due to pressure changes, observed through transport measurements.
- Key indicators like variations in Shubnikov-de Haas oscillations and changes in effective cyclotron mass indicate band deformation and potential emergence of massless behavior as the pressure approaches a critical level for the topological phase transition.
