The interplay of topology, magnetism, and correlations gives rise to intriguing phases of matter. In this study, through state-of-the-art angle-resolved photoemission spectroscopy, density functional theory, and dynamical mean-field theory calculations, we visualize a fourfold degenerate Dirac nodal line at the boundary of the bulk Brillouin zone in the antiferromagnet YMnGe. We further demonstrate that this gapless, antiferromagnetic Dirac nodal line is enforced by the combination of magnetism, space-time inversion symmetry, and nonsymmorphic lattice symmetry.

- - The study observes a new type of order, called intra-unit-cell nematic order, in the kagome metal ScVSn, which breaks the crystal's rotational symmetry.
- - Using advanced scanning techniques, researchers found stripe-like patterns and specific electron behavior that demonstrate this symmetry breaking and the deformation of the Fermi surface.
- - This research connects the concepts of electronic nematicity with kagome physics, offering insights into how symmetry-broken phases can emerge in materials with correlated electrons.
Article Synopsis
- Topology and interactions are key concepts in understanding quantum matter, leading to three main research directions: competition between interactions, interplay of interactions with topology, and resulting novel phases from combined topological orders.
- This study reveals a unique 'hybrid' topological phase in arsenic using advanced techniques, demonstrating both strong and higher-order topology through specific surface features.
- The findings suggest potential for exploring and utilizing different band topologies and their conduction properties in future quantum or nano-devices.
Creating Patient Context: Empathy and Attitudes Toward Diabetes Following Virtual Immersion.
J Diabetes Sci Technol
September 2023
Background: Pandemic circumstances created challenges for doctor of physical therapy (DPT) students to understand social determinants of health (SDH) in clinical rotations. Instead of canceling clinical rotations, a virtual reality cinema (cine-VR) education series was implemented. The purpose of this project is to describe the effect of this simulated immersion on student empathy and attitudes toward diabetes.
