An efficient material search for room-temperature topological magnons
Lu (OSU Physics), Goldberger (OSU Chemistry), Doan-Nguyen(OSU MSE)
IRG-2 developed a symmetry-based approach that uses only few inputs, to carry out an efficient yet systematic search for topological magnons in magnetic insulators. Robust against disorders and decoherence, they serve as potential platforms for magnon-based spintronic devices.

Confined Monolayer Ag as a Large Gap 2D Semiconductor
Shih, MacDonald, Li (UT MRSEC); Crespi, Robinson (Penn State MRSEC)
By mapping momentum-resolved electronic states using time-resolved and angle-resolved photoemission spectroscopy, researchers recently revealed that monolayer Ag confined between bilayer graphene and SiC is a large gap (>1 eV) 2D semiconductor, consistent with ab initio GW calculations.

Ferroelectric Superconductivity in a Transition Metal Dichalcogenide
A. Saha, T. Birol, R. Fernandes (IRG-1)
For the first time, a team comprised of two IRG-1 theorists (Birol and Fernandes) working with experimentalists from other institutions (including the Columbia MRSEC) showed the coexistence of ferroelectricity (i.e., electrostatically switchable macroscopic dipole moment) and superconductivity in a two-dimensional superconductor.
