  • Instabilities in chiral plasmas can amplify electromagnetic waves, raising the question of whether chiral solids behave similarly. Now a magneto-chiral instability is demonstrated in tellurium, observed as growing terahertz emission after photoexcitation.

  • Femtosecond pulses from X-ray free-electron lasers offer a powerful method for studying charged collective excitations in materials, and provide a potential route to identifying bosonic quasiparticles in condensed-matter systems.

  • Orbital order is important to many correlated electron phenomena, including colossal magnetoresistance and high-temperature superconductivity. A study of a previously unreported structure transition in KCuF3 suggests that direct interorbital exchange is important to understanding such order.

  • Transport measurements show that nematic fluctuations near a phase transition increase the temperature at which superconductivity occurs by a factor of nearly six. This happens in a non-magnetic nickel-based compound.

  • Recent experiments on the dynamical charge response of strange metals reveal unusual features such as momentum-independent continuum of excitations and unconventional plasmon decay. Here the authors present a phenomenological theory based on the analogy to classical fluids near a jamming-like transition.

  • Evidence is presented for a Pines’ demon as a three-dimensional acoustic plasmon in the multiband metal Sr2RuO4 from momentum-resolved electron energy-loss spectroscopy using a collimated, defocused beam with high momentum resolution.

  • It has been predicted that the quasi-one-dimensional charge density wave material (TaSe4)2I hosts Kramers-Weyl fermions, but direct spectroscopic evidence of this is limited. Here, ARPES and theoretical calculations reveal signatures that may indicate the presence of Kramers-Weyl fermions.
