Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, amongst other things, because they lead ...

When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and ...

Researchers have made germanium superconducting for the first time, a feat that could transform computing and quantum technologies. Using molecular beam epitaxy to embed gallium atoms precisely, the ...

The material exhibits an exceptionally low lattice thermal conductivity of ~0.18 W/m·K, placing it among the lowest known for crystalline solids.

For a long time, scientists associated crystal structures with an ordered arrangement of atoms in a repeating lattice-like pattern, believing it to be the most stable configuration. However, by the ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

Atomic orbitals (red & blue), which determine how far electrons can move around their originating atom in a material, can trap those electrons in place—a new source of frustration that researchers can ...
