Magnetic structure in the two-dimensional van der Waals ferromagnet Fe3_3GaTe2_2

High-quality single crystals of the two-dimensional van der Waals ferromagnet Fe3_3GaTe2_2 were successfully synthesized and characterized, revealing a hexagonal structure with distinct magnetic moments on inequivalent iron sites and a Curie temperature of approximately 355–360 K, which is attributed to a contracted interatomic distance that strengthens exchange interactions compared to Fe3_3GeTe2_2.

Polarizable Embedding QM/MM for Periodic Systems

This paper presents a general polarizable embedding QM/MM scheme for periodic systems that couples density functional theory with a multipole-expanded water model featuring anisotropic polarizabilities, utilizing far-field multipole expansions and short-range damping to achieve high accuracy and smooth convergence while preventing over-polarization.

Families of planar lattices with arbitrarily high TcT_{\rm c} for the ferromagnetic Ising model

This paper constructs families of periodic planar lattices, specifically Apollonian lattices, that achieve arbitrarily high critical temperatures for the ferromagnetic Ising model by demonstrating that TcT_{\rm c} scales logarithmically with the maximal coordination number and conjecturing this family to be optimal for such systems.

Orbital and Spin Nernst Effects in Monolayers of Transition Metal Dichalcogenides

This paper demonstrates that monolayer transition metal dichalcogenides serve as an ideal platform for observing both orbital and spin Nernst effects, revealing that the orbital Nernst effect arises intrinsically without spin-orbit coupling while the spin Nernst effect scales with it, with both phenomena being tunable via doping in semiconducting MoS2_2 and intrinsically present in metallic NbS2_2.

A molecular perspective on coordination, screening, and emergent length scales in lithium electrolytes

This perspective proposes a unified multiscale framework that integrates local coordination, mesoscopic organization, and macroscopic transport to explain how increasing electrolyte concentration couples these phenomena, thereby necessitating a holistic approach to rational lithium electrolyte design.

Ytterbium charge state and stabilization in the Ba(Ca)F2_2 host by electron paramagnetic resonance and infrared photoluminescence

This study systematically compares ytterbium incorporation in BaF2_2 and CaF2_2 single crystals using multiple characterization techniques to demonstrate that the host cation identity governs the stabilization balance between Yb2+^{2+} and Yb3+^{3+} charge states and dictates local defect formation and optical properties.

Non-homogeneous structure of complex concentrated alloys: Effect of intrinsic strain

This paper demonstrates through theoretical analysis and experimental observation that the non-homogeneous distribution of atoms in complex concentrated alloys reduces overall system energy by compensating for tensile and compressive strain fields, thereby highlighting the critical role of local chemical and structural heterogeneity in determining thermodynamic stability.
