Unified Statistical Theory of Heat Conduction in Nonuniform Media

This paper presents a unified statistical theory of heat conduction in nonuniform media by deriving a causal spatiotemporal kernel via the Zwanzig projection-operator formalism, which microscopically encodes memory, nonlocality, and heterogeneity to seamlessly bridge classical diffusion, hydrodynamic, and quasi-ballistic transport regimes while recovering conventional coefficients as coarse-grained limits.

Stoichiometry-Controlled Structural Order and Tunable Antiferromagnetism in FexNbSe2\mathrm{Fe}_{x}\mathrm{NbSe_2} (0.05≤x≤0.380.05 \le x \le 0.38)

This study establishes a precise stoichiometry-structure-magnetism correlation in FexNbSe2\mathrm{Fe}_{x}\mathrm{NbSe_2}, revealing that a well-ordered 2a0×2a02a_0 \times 2a_0 Fe superlattice at x=0.25x=0.25 maximizes antiferromagnetic coupling (TN=175KT_{\mathrm{N}}=175\mathrm{K}) while deviations from this optimal ordering induce a complex sequence of magnetic phase transitions from paramagnetism to spin-glass and back.
