Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more ...

Quantum entanglement is challenging researchers to understand how photons seemingly influence each other instantaneously.

In this module, we introduce the general definition of angular momentum operator based on rotation operator. This general definition allows both orbital and spin angular momentum. We then derive the ...

131, No. 995, 2019 January Angular Momentum of Stars and their Plan... To understand the distribution of angular momenta between host stars and their planets, we estimate the spin angular momentum ...

In addition to having mass and electric charge, electrons also possess spin—a form of intrinsic angular momentum. In some crystalline materials, nearby electrons orient their spins relative to ...
