Atoms passing through walls: Quantum tunneling of hydrogen within palladium crystal

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the ...

Mirror symmetry prompts ultralow magnetic damping in 2D van der Waals ferromagnets

Two-dimensional (2D) van der Waals (vdW) ferromagnets are thin and magnetic materials in which molecules or layers are held together by weak attractive forces known as vdW forces. These materials have proved to be promising ...
