The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that ...

A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.

Topological Kondo insulators represent a unique class of strongly correlated materials in which the interplay between localised f-electron states and itinerant conduction electrons gives rise to a ...

Illustration of a molecular Kondo-box singlet formed by large orbital overlap between symmetry-matched dπ and π orbitals in an atomic/molecular system on a metal surface. Recently, a research group ...

The hardness of materials is determined by the strength of the chemical bonds that are formed between the electrons of the neighbouring atoms. For example, the bonds in diamond are very strong, so it ...
