Generative reconstruction of 2D and 3D polycrystalline microstructures using symmetrized hyperspherical harmonics

This paper presents an open-source, differentiable framework implemented in MCRpy that utilizes symmetrized hyperspherical harmonics and advanced spatial correlation descriptors to efficiently generate high-fidelity 2D and 3D polycrystalline microstructures from limited 2D orientation data, thereby enabling robust structure-property linkage studies for materials design.

Current induced magneto-optical Kerr effect as a probe of Dirac carriers in Bi $_{1-x}$ Sb $_x$ alloy

This study demonstrates that current-induced magneto-optical Kerr effect (MOKE) in Bi $_{1-x}$ Sb $_x$ alloys serves as a powerful probe for identifying Dirac carriers, evidenced by a signal magnitude exceeding that of transition metals and a distinct scaling relationship with resistivity and mobility that aligns with Dirac electron models rather than conventional parabolic band theories.

Hopf Semimetals

This paper constructs four-dimensional two-band topological semimetals, termed "Hopf semimetals," which utilize unstable homotopy to host nodal lines with Hopf flux and exhibit unique gapless surface and corner states, including Fermi arcs, drumhead states, and Fermi surfaces.

Fragmented charged domain wall below the tetragonal-orthorhombic phase transition in BaTiO3

This study reveals that the dramatic drop in conductivity of head-to-head charged domain walls in barium titanate below the tetragonal-orthorhombic phase transition is caused by the walls fragmenting into alternating charged and uncharged micron-scale segments, which disrupts the macroscopic conductive channel.

Chirality-Induced Spin Selectivity: Nonlinear Spin Response from Electron-Phonon Scattering

Using first-principles spatiotemporal density-matrix dynamics, this study reveals that in trigonal selenium, nonlinear spin accumulation driven by intervalley scattering mediated by chiral phonon angular momentum distinguishes the chirality-induced spin selectivity (CISS) effect from the linear collinear Edelstein effect.

Random phase approximation-based local natural orbital coupled cluster theory

This paper introduces the random phase approximation (RPA) as a robust alternative to second-order Møller-Plesset perturbation theory (MP2) within the local natural orbital-based coupled-cluster (LNO-CC) framework, demonstrating that RPA-based LNO-CC maintains accuracy for systems with sizable energy gaps while offering significantly faster convergence for metallic systems.

Fast Generation of Pipek-Mezey Wannier Functions via the Co-Iterative Augmented Hessian Method

This paper introduces the $k$ -CIAH algorithm, a $k$ -point extension of the second-order co-iterative augmented Hessian method for Pipek-Mezey Wannier function localization, which achieves computational efficiency 2–3 times higher than first-order $k$ -space approaches and orders of magnitude faster than $\Gamma$ -point methods while maintaining optimal $O(N_k^2 n^3)$ scaling.

Bridging perturbation and variational approaches in brittle fracture

This paper introduces a variational reduced-order model that bridges perturbation and variational fracture theories to efficiently simulate 3D brittle crack propagation in heterogeneous media, revealing how disorder intensity and mode mixity govern the transition from smooth to intermittent growth and the crossover between disorder-induced weakening and toughening.
