  • As indicated by direct band-structure measurements and calculations, tiny native imperfections in bilayer graphene are sufficient to cause the generation of coexisting massive and massless Dirac fermions. The massless spectrum is robust against strong electric fields and has a closed-arc topology consisting of a unique chiral pseudospin texture.

  • The Mott metal-insulator transition, driven by electron-electron interactions, is challenging to control directly in solid-state systems, especially within the complex environments of neuromorphic devices. Here, the authors demonstrate that interface-induced screening in LaTiO₃/SrTiO₃ heterostructures can continuously tune interaction strength, enabling an isothermal Mott transition, thus offering a promising method for manipulating Mott physics through correlation control.

  • Reversible and rapid switching between metallic and insulating states is key for next-generation memory devices, but identifying and studying such materials is challenging. Here, using angle-resolved photoemission spectroscopy, the authors investigate a metastable metallic state of 1T-TaS2 when exposed to short current pulses.
