Systematic and accurate anharmonic formation free energies of metastable defects via a constrained Bayesian Adaptive Biasing Force framework

This paper introduces a constrained Bayesian Adaptive Biasing Force (BABFc) framework that enables the systematic, accurate, and efficient calculation of anharmonic formation free energies for metastable defects in complex, highly anharmonic energy landscapes without requiring defect-specific collective variables, as demonstrated through extensive applications to interstitial and vacancy configurations in bcc α\alpha-Fe.

Quasi-one-dimensional topological band structure and van Hove singularities in monolayer TaIrTe4_4 from laser μ\mu-ARPES

Using laser micro-ARPES, this study reveals that monolayer TaIrTe4_4 possesses a quasi-one-dimensional band structure with a van Hove singularity at a carrier density inconsistent with transport anomalies, suggesting that strong electron correlations play a secondary role in the material's quantum spin Hall phase.

Identification of the length scale parameter of simplified strain gradient elasticity from standard Mode I fracture tests

This paper presents a method to identify the single length scale parameter of simplified strain gradient elasticity from standard Mode I fracture tests, deriving explicit formulas for brittle materials and regression relations for quasi-brittle materials to capture non-classical size effects using experimental data.

Soft and chiral phonons in chiral phase of K3NiO2

This study combines Raman scattering experiments and theoretical calculations to confirm that the structural phase transition in K₃NiO₂ near 400 K is driven by a soft phonon at the Z point, which splits into A₁ and B₁ modes in the low-temperature chiral phase, while also revealing that certain phonons with nonzero momentum in this phase exhibit pronounced circular atomic motion and nonzero angular momentum.

Chemical Control of Electronic Structure and Topology in Tellurium-Encapsulated Silicene

First-principles calculations demonstrate that substituting group-III elements (B, Al, Ga, In) in Te-encapsulated silicene monolayers systematically tunes their electronic and topological properties, driving a transition from trivial semiconductors to a quantum spin Hall insulator in the In-based variant.
