Direct Imaging of Hydrogen‐Driven Dislocation and Strain Field Evolution in a Stainless Steel Grain
Advanced Materials, EarlyView.Using in situ Bragg coherent X‐ray diffraction imaging, 3D nanoscale strain maps of a stainless steel grain were measured during hydrogen charging. Results show dislocation relaxation and climb, elucidating the role of point defects in hydrogen‐modified deformation behavior.

Nature Communications, 2019 Three-dimensional (3D) gapless topological phases can be classified by the dimensionality of the band degeneracies, including zero-dimensional (0D) nodal points, one-dimensional (1D) nodal lines, and two-dimensional (2D) nodal surfaces. Both nodal points

, 2017 Topological nodal-line semimetals are characterized by one-dimensional lines of band crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologically nontrivial configurations. In this Rapid Communication, we introduce the

Inventiones Mathematicae, 1986 Denote by \(V(d,g)\) the family of all irreducible nodal algebraic plane curves of degree \(d\) and genus \(g.\) A well known conjecture of Severi, recently proved by \textit{J. Harris} [Invent. Math. 84, 445-461 (1986; Zbl 0596.14017)], claims the irreducibility of V(d,g).

Observation of Non-Abelian Nodal Links in Photonics.
Physical Review Letters, 2019 In crystals, two bands may cross each other and form degeneracies along a closed loop in the three-dimensional momentum space, which is called nodal line. Nodal line degeneracy can be designed to exhibit various configurations such as nodal rings, chains,

Altermagnetic Band Splitting in 10 nm Epitaxial CrSb Thin Films
Advanced Materials, EarlyView.Thin film altermagnets are attractive for potential spintronic applications. How thin can we make an altermagnet before quantum confinement perturbs the distinctive band structure? This paper uses angle‐resolved photoemission spectroscopy to show that the canonical g‐wave altermagnet, NiAs‐type CrSb, grown by molecular beam epitaxy, preserves its ...
