Summary: This paper theoretically examines the continuity between atomic and molecular Fermi superfluids in a Bose-Fermi mixture near the Feshbach resonance. A mean-field framework is constructed based on the perturbative expansion of the b-f-F Feshbach coupling in a two-channel model. The resulting effective Hamiltonian exhibits a continuity between atom-atom to molecule-molecule Cooper pairings and becomes equivalent to the two-band-superconductor model with a pair-exchange coupling.

Summary: This paper studies the spinorial wave equations, namely the Dirac and the Klein-Gordon equations, as well as the greybody radia-tions and quasinormal modes of the charged Taub NUT black hole. By using the Dirac equation, we obtain the fermionic greybody factors and quasinormal modes. For the bosonic greybody factors and quasinormal modes, we study the Klein-Gordon equation in the CTNBH geometry and derive the radial equation. We then investigate the effect of the NUT parameter on the effective potential.

Summary: Aliovalent substitution is an effective strategy to improve the ionic conductivity of solid electrolytes. Substituting SbS43- with WS42- in Na2.9Sb0.9W0.1S4 significantly enhances its ionic conductivity, reaching 41 mS cm-1 at room temperature. Despite the change in the diffraction pattern, the short-range order of Na2.9Sb0.9W0.1S4 remains tetragonal. The study highlights the importance of analyzing the local structure of ionic conductors to understand their transport mechanisms and develop faster ionic conductors.

Summary: This review discusses the impact of nematicity on the relationship between antiferromagnetic fluctuations and superconductivity in the S-substituted FeSe, FeSe1-xSx, system. Experimental evidence shows that antiferromagnetic fluctuations play a crucial role in the Cooper pairing mechanism and the superconducting transition temperature (Tc) is roughly proportional to the fluctuations. However, the presence of nematicity weakens the effectiveness of antiferromagnetic fluctuations in enhancing superconductivity.

Summary: The Default Mode Network (DMN) and the Theory of Mind (ToM) networks are important in understanding self-neurocognition. While the DMN is associated with introspection, the ToM is involved in perspective-taking. However, there is no research on the overlap between DMN and ToM in relation to causal effects induced by psychedelics, and their precise relationship remains unknown. Psychedelics alter self-perception and modulate these networks, which can provide insights into this relationship.

Summary: This study investigated the potential correlation between mean arterial pressure (MAP) and portal venous pressure (PVP) in rats with healthy livers. The results showed that changes in MAP are followed by changes in PVP with a distinct time lag, indicating a cause-and-effect relationship. The study also revealed that Sildenafil influences portal pressure. Further studies should be conducted in a model with cirrhotic livers to evaluate the effects of vasoactive drugs for therapy of portal hypertension.

Summary: This study used a high-energy planetary mill to mechanically activate chalcopyrite in different modes. Wet-milling resulted in higher BET surface area, while dry milling significantly affected the microstructural changes of chalcopyrite. Samples subjected to dry milling showed the highest copper extraction efficiency. The results suggest that mechanical activation parameters play a crucial role in enhancing leaching efficiency of chalcopyrite.

Summary: The relationship between Atlantic meridional overturning circulation (AMOC) variability and high-latitude North Atlantic buoyancy changes is influenced by both driving and responding roles of temperature and salinity. Analysis of control simulations reveals that North Atlantic buoyancy-forced AMOC variability is present in both oscillatory and red-noise regimes, with the latter showing weaker buoyancy-driven AMOC changes and additional multidecadal/centennial AMOC behavior unrelated to North Atlantic buoyancy forcing.

Summary: This study presents a comprehensive investigation on the nematic fluctuations in a non-superconducting iron pnictide system, revealing the crucial role of the interplay between local spins and itinerant electrons on Fermi surfaces. The results indicate that the in-plane resistivity anisotropy highly depends on the Cr dopings and the type of charge carriers, and the orbital degree of freedom may behave differently from the spin degree of freedom.

Summary: A hallmark of strongly correlated quantum materials is the rich phase diagram resulting from competing and intertwined phases. Recently, such rich phase diagrams have also been shown in correlated topological materials. This study reports the discovery of CDW in the antiferromagnetic ordered phase of kagome lattice FeGe, which is caused by the combination of electron-correlated AFM order and van Hove singularities-driven instability.

Summary: In this study, pressure-tuned and ultra-low temperature muon spin spectroscopy was used to uncover the unconventional nature of superconductivity in RbV3Sb5 and KV3Sb5. It was found that at ambient pressure, time-reversal symmetry breaking charge order was observed in RbV3Sb5, and the superconducting state displayed a nodal energy gap and reduced superfluid density. Applying pressure suppressed the charge-order transitions, increased the superfluid density, and progressively evolved the superconducting state from nodal to nodeless. The optimal superconductivity state was found to break time-reversal symmetry. These results offer unique insights into the nature of the pairing state and highlight the tunable nodal kagome superconductivity competing with time-reversal symmetry-breaking charge order.

Summary: This study reports the first observation of coherent hybridization of magnons and phonons in monolayer antiferromagnet FePSe3, which exhibits nontrivial band inversion between longitudinal and transverse optical phonons in zero magnetic field. The presence of magnetic-field-controlled topological phase transition is theoretically guaranteed by the spin and lattice symmetry, as confirmed by nonzero Chern numbers calculated from the coupled spin-lattice model. The 2D topological magnon-phonon hybridization potentially paves the way for quantum phononics and magnonics with an ultrasmall footprint.

Summary: Electron correlations in quantum materials can lead to emergent orders, such as the topological states found in kagome lattice materials. These emergent orders are a result of the specific electronic band structure associated with the kagome lattice geometry. Various correlated electronic phases, including magnetism and superconductivity, have been discovered in kagome lattice materials. In this study, the authors observe all three electronic signatures of the kagome lattice in FeGe using angle-resolved photoemission spectroscopy and provide evidence for the interplay between magnetism and charge order in this material.

Summary: Understanding the interplay between superconductivity and magnetism in EuTe2 is achieved through high pressure studies. A structural transition and superconductivity are observed at different pressures. Strong couplings between local moments and conduction electrons are observed in the low-pressure phase, while the high-pressure phase loses magnetism and has a lower upper critical field.

Summary: In this research, the phase stability of 2D/3D h-BN/c-BN nanocomposites is investigated, showing that the coexistence of the two phases can result in strong nonlinear optical properties and low thermal conductivity at room temperature. Spark-plasma sintering of the nanocomposites demonstrates complete phase transformation to 2D h-BN with improved crystalline quality, where the nucleation and growth kinetics are possibly governed by 3D c-BN. These findings provide insights into phase engineering of BN polymorph-based nanocomposites with desirable properties for optoelectronics and thermal energy management applications.

Summary: In this study, neutron scattering was used to investigate CoZnMo3O8 and found a wave-vector-dependent excitation continuum at low energy that disappears with increasing temperature. Although these excitations resemble a spin excitation continuum in a quantum spin liquid state, their presence in CoZnMo3O8 is due to magnetic intersite disorder-induced dynamic spin states with peculiar excitations. Therefore, this study provides direct experimental evidence for the presence of a disorder-induced spin excitation continuum.
