Theoretical understanding of heavy-fermion superconductors has just slipped a notch or two, says a team of experimentalists. Researchers from the University of Illinois at Urbana-Champaign and Los ...

Atomic-scale optical spectroscopy revealed huge Raman scattering when an atomic point contact is formed between a plasmonic silver tip and a single-crystal silicon surface. The huge Raman scattering ...

The discovery of Weyl semimetals 1,2,3,4,5,6,7,8,9,10,11 facilitated the realization of Weyl fermions in condensed matter systems after more than 80 years of their theoretical discovery 12. In quantum ...

Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to ...
