Thickness-Dependent Interlayer Coupling and Semiconductor-to-Semimetal Crossover in Arsenene Multilayers

By combining diffusion quantum Monte Carlo and density functional theory, this study reveals that interlayer coupling in arsenene multilayers is thickness-dependent rather than solely registry-determined, leading to a structural evolution from A1_{1}A1_{1} to bulk-like A1_{1}B−1_{-1} stacking and a concurrent semiconductor-to-semimetal crossover driven by enhanced interlayer As pz_{z} hybridization.

Interplay of Altermagnetism and Coupled Quasi-Altermagnetic states in Sliding Two-dimensional Square Lattice

This paper proposes a new classification of altermagnetic states in two-dimensional square lattices, identifying a distinct "coupled quasi-altermagnetic" phase where interlayer sliding controls reversible non-relativistic spin splitting, and demonstrates this mechanism using Mn2WS4 and its Janus derivative Mn2WS2Se2.

Terahertz frequency upconversion by coherently driving charge dynamics in the InSb/CdTe heterostructure

This paper demonstrates efficient in-plane magnetic field-induced second-harmonic generation and significant third-harmonic generation in an InSb/CdTe heterostructure, attributing these effects to orbital-Zeeman corrections and Drude-like charge dynamics to establish a general route for terahertz frequency upconversion in high-mobility materials.

Hartree-Fock Limit for Energies in Solids

This study presents a refined linearized augmented plane wave (LAPW) method that consistently constructs radial basis functions and core orbitals with the Hartree-Fock Hamiltonian to achieve micro-Hartree precision in total energies, thereby providing rigorous all-electron benchmarks for semiconductors and insulators while validating the practical accuracy of standard semi-local approaches for relative energies.

On representation of macroscopic crack in periodic fine-scale discrete mechanical models

This study evaluates novel boundary conditions for representing macroscopic cracks in periodic discrete models of concrete, finding that while Tessellation boundary conditions consistently produce well-defined localization bands, Percolation-path-aligned conditions suffer from spurious multi-band formation and displacement-jump augmented circular models sometimes fail to improve upon standard periodic results.

Exciton Transport in Disordered Perovskite Nanocrystal Solids

This study demonstrates that energetic disorder, driven by quantum confinement in monodisperse nanocrystals with long alkyl chain ligands, is the dominant factor limiting exciton transport in lead halide perovskite nanocrystal solids, outweighing the effects of structural disorder.

Breaking symmetry to create a parallel-plate varactor dielectric with unparalleled microwave performance

By engineering a Ruddlesden-Popper dielectric thin film with broken out-of-plane symmetry, researchers have successfully created a low-loss, voltage-tunable parallel-plate varactor that achieves a tenfold improvement in performance at 10 GHz, overcoming previous structural limitations to enable advanced monolithic microwave integrated circuits.

Polymer-polymer interdiffusion: effects of entanglements and a polymeric source

This paper investigates polymer-polymer interdiffusion in both entangled and unentangled regimes with and without a polymeric source using a two-fluid formalism to derive scaling relations and analytical solutions that are validated by numerical simulations, revealing that while a source term disrupts self-similarity, the diffusing front retains similar spatial characteristics.

Controllable Quantum Spin Hall Phases in Bi2_2Te3_3-Family van der Waals Heterobilayers

This study demonstrates that stacking two trivial quintuple layers from the Bi2_2Te3_3 family can induce controllable quantum spin Hall phases in van der Waals heterobilayers, where the topological edge states can be switched on or off via external strain and electric fields while remaining robust against interlayer twisting.
