Understanding the behavior of QCD matter under strong coupling remains a difficult task due to its inherently non-perturbative character. In this context, we investigate a two-flavor hard-wall holographic model to explore finite-density QCD at zero temperature, incorporating effects from a nonzero quark mass. The dense matter phase is described by solving the classical equations of motion within a homogeneous ansatz. To establish a connection between the bulk gravity theory and boundary QCD observables, we perform holographic renormalization and formulate the corresponding holographic dictionary. In analyzing the phase structure, we highlight the importance of introducing an IR boundary term at the hard-wall cutoff. Within this setup, we identify a phase of baryonic matter characterized by a large baryon number density and a significantly reduced chiral condensate. We derive the equation of state for this phase and use it to compute the mass-radius relation for neutron stars.

We analyze powder-averaged inelastic neutron scattering and magnetization data for the distorted honeycomb compound CuSbO using a first-order dimer expansion calculation and quantum Monte Carlo simulations. We show that, in contrast to the previously proposed honeycomb lattice model, CuSbO accommodates interacting dimerized spin chains with alternating ferromagnetic-antiferromagnetic couplings along the chain. Moreover, unlike the typical couplings observed in other Cu-based distorted honeycomb magnets, the spin chains in CuSbO primarily couple through an antiferromagnetic coupling that arises between the honeycomb layers, rather than the expected interchain coupling in the layers. This finding reveals a different magnetic coupling scheme for CuSbO. In addition, utilizing X-ray spectroscopy and transmission electron microscopy, we also refine the crystal structure and stacking-fault model of the compound.

To investigate the phonon dynamics of iron in the heavily hydride-ion-substituted region of LaFeAsOH (), Fe nuclear resonant inelastic scattering measurements were performed over a wide temperature range from 5 to 300 K on two polycrystalline samples with and 0.51, which exhibit superconducting and antiferromagnetic ground states, respectively. The resulting inelastic scattering spectra revealed distinct differences between the two compositions. The Fe phonon density of states (PDOS) exhibits a pronounced peak at 15 meV for , whereas this peak is absent in . Density functional theory calculations support the interpretation that the PDOS peak at 15 meV is associated with the optical vibrational modes of Fe atoms along the nearest-neighbor direction, mediated by As atoms. The calculations further suggest that the suppression of the PDOS peak at 15 meV for originates from in-plane electronic inequivalence. These findings suggest that signatures of electronic nematicity may persist over a wide temperature range in the composition, which exhibits magnetic and structural order, whereas such signatures are almost absent in the superconducting composition.
