The authors present measurements by soft-x-ray angle-resolved photoemission spectroscopy of hexagonal diboride AlB, which is a cousin material of the well-known high-temperature superconductor MgB. Via accurate determination of the three-dimensional bulk band structure corroborated by first-principles band-structure calculations, the authors demonstrate that AlB displays an exotic Dirac-nodal-line structure with anisotropic Dirac-cone energy band. This intriguing electronic structure provides an excellent platform to study the interplay among the line node, low-energy excitations, and topological transport properties.

The authors present a derivation of finite-size corrections to entanglement entropies that possess an internal symmetry. They show that entanglement entropy is equally distributed among the different sectors of that internal symmetry. Its value is given by the standard area-law-violating logarithmic term, which depends on the central charge , minus a double logarithmic correction related to the zero-temperature susceptibility. They present a very efficient way to determine the central charge and the Luttinger parameter. This opens the possibility that the measurement of these quantities can be successfully pursued in an optical lattice. The analytical predictions are verified against numerical results obtained by DMRG.

CaRuO has long been an enigmatic compound due to reports of possible non-Fermi-liquid behavior and its proximity to a magnetic quantum critical point. Through a combination of molecular beam epitaxy growth and angle-resolved photoemission, the authors reveal that the large rotations of the RuO octahedra result in a complex Fermi surface with multiple quasiparticle bands and hybridization gaps lying very close to the Fermi energy. The measurements demonstrate a highly band-dependent mass renormalization, where the dispersion and temperature dependence of the heavy bands show intriguing parallels to heavy-fermion systems. These results provide a unified framework for explaining the peculiar properties of CaRuO and demonstrate the importance of octahedral rotations in shaping the physical properties of the ruthenates.
