  • 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, indicating it being a weak topological insulator.

  • Topological insulators like bismuth selenide exhibit Dirac surface states in which the electron spin is locked with the crystal momentum. Using spin- and angle-resolved photoemission spectroscopy, the authors observe a new kind of coupling between the spin and orbital texture of the Dirac cones.

  • Recently, superconductivity near 80 K was observed in La3Ni2O7 under high pressure, but the mechanism is debated. Here the authors report angle-resolved photoemission spectroscopy measurements under ambient pressure, revealing flat bands with strong electronic correlations that could be linked to superconductivity.

  • Measurements of the electronic structure of a trilayer cuprate superconductor suggest that its high critical temperature is explained by the different doping levels of the layers. The combination of underdoped inner layer and overdoped outer layers supports superconductivity.

  • According to conventional wisdom, angle-resolved photoemission spectroscopy (ARPES) can only measure the magnitude of the superconducting gap but not its phase. Here, the authors propose a new method to directly detect the superconducting gap phase using ARPES and validate this technique on a cuprate superconductor.

  • How superconductivity emerges out of the antiferromagnetic insulating state of the cuprates is unclear. High-resolution ARPES measurements reported by Zhouet al.suggest that this emerges at the point where antiferromagnetic order disappears and the nodal gap of its electronic structure falls to zero.
