Hidden Singularity and Fractal Dimensions for Extended Harper Operators

This paper establishes that the spectra of extended Harper operators in the zero-measure regime possess finite 1/21/2-dimensional Hausdorff measure and a lower box dimension of at most 1/21/2 (improving to 1/31/3 on the isotropic critical boundary) by utilizing a family of unitary transformations to map these operators to singular Jacobi representatives, thereby enabling the construction of specific interval covers that yield these fractal dimension bounds and demonstrate cases where the box-counting dimension fails to exist.

Charge state and hydration of vacancies in silicon and silicon carbide in contact with water: A grand-canonical first-principles stability map

This study employs grand-canonical first-principles calculations to map the stability of silicon and silicon carbide vacancies in contact with water, revealing that their charge states and hydration levels are jointly determined by pH and electrode potential, with hydrogen binding cooperatively to silicon vacancies but failing to passivate carbon vacancies without cathodic bias.

Wrinkling dynamics of thin crystalline sheets and its dependency on topological defects

Using a Surface Phase-Field-Crystal-Helfrich model, this study reveals that while crystalline defects do not alter the scaling laws of wrinkling coarsening, they significantly influence the onset, wavelength, and pattern irregularity of wrinkles by promoting a higher density of wrinklons and modifying long-term morphological evolution.

Kagome goldene with flat bands and Dirac nodal line fermions via line-graph epitaxy

This paper introduces "line-graph epitaxy" as a novel method to synthesize a single-atomic-layer kagome lattice of gold (goldene), which exhibits strong electron correlation effects via a flat band and hosts dual Dirac nodal lines through proximity effects with its substrate.
