Weyl fermions discovered in another class of materials

A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: they move through a material in a well ordered manner that practically never lets them collide with each ...

Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...

Approaching the magnetic singularity

In many materials, electrical resistance and voltage change in the presence of a magnetic field, usually varying smoothly as the magnetic field rotates. This simple magnetic response underlies many applications including ...
