Scanning tunneling microscopy of resonant-impurity in altermagnets: dual Fano resonance and Landau-quantization-induced nodal spin contrast

This paper theoretically demonstrates that scanning tunneling microscopy of resonant impurities on altermagnetic substrates reveals dual Fano resonances and spin-selective tunneling in zero field, as well as distinct nodal spin contrast patterns under strong magnetic fields, establishing the technique as a phase-sensitive local probe for altermagnetic band anisotropy.

Force-Isosurface Simulations Probe the Limits of High-Resolution AFM on Three-Dimensional Molecules

This study utilizes probe-particle simulations to demonstrate that force-isosurface imaging, derived from three-dimensional force fields, can effectively overcome the limitations of conventional high-resolution AFM by preserving molecular framework details and enabling quantitative orientation recovery for non-planar and three-dimensional molecules.
