  • The authors study the non-centrosymmetric achiral material InxTaS2 by angle-resolved photoemission spectroscopy and quantum oscillations. They find that it hosts an “ideal” Kramers nodal line, well isolated at the Fermi level.

  • Some materials can display magnetic order despite having spin-singlet ground state on individual magnetic sites. This arises due to exchange interactions mixing excited crystal electric field states. Here, Gao et al study and example of such a system, Ni2Mo3O8, and find that crystal electric field states in both the paramagnetic and antiferromagnetic states exhibit dispersive excitations.

  • Whether an actual Mott insulator phase exists in iron pnictides remains elusive. Here, Songet al. demonstrate an antiferromagnetic insulator phase persisting above the Néel temperature in NaFe1−xCuxAs, indicative of a Mott insulator, highlighting the role of electron correlations in high-Tcsuperconductivity.

  • LOFAR radio observations, complemented by ultraviolet and visible light images, of the powerful class-X8.2 solar flare of 10 September 2017 pinpoint the location of multiple shock signatures of electron beams (herringbones) along the expanding coronal mass ejection.

  • Kramers Nodal Lines (KNLs) have been theoretically proposed as special Weyl line degeneracies connecting time-reversal invariant momenta, but their observation in quantum materials is not established. Combining ARPES experiments with DFT calculations, the authors identify SmAlSi and its isostructural family as viable materials to host KNLs.

  • The reversal of spin chirality in the absence of any externally applied field would substantially broaden the use of chiral magnets for applications in spintronic devices. In this manuscript the authors demonstrate the spontaneous reversal of spin chirality in the topological magnet EuAl4 using resonant elastic x-ray scattering.

  • The Dicke model, describing the cooperative coupling of an ensemble of two-level atoms with a single-mode light field, has a rich phenomenology in quantum optics and quantum information, but its analytical or numerical solution is beyond current reach. Here, a solid-state quantum simulator of an extended Dicke model is achieved using ErFeO3 crystals, where terahertz spectroscopy and magnetocaloric effect measurements reveal an atomically ordered phase in addition to the expected superradiant and normal phases.
