Electron beams have transcended their traditional roles in imaging and lithography to become vital platforms for exploring fundamental quantum phenomena. Central to recent advances is the manipulation ...

How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation to determine the speed of the satellite as a function of the distance R from O to P. Since the ...

A chemical reaction can be understood in detail at the quantum state-resolved level, through a combined study of molecular crossed beam experiments and theoretical quantum molecular reaction dynamics ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. You can take any particle in the Universe and isolate it from ...

Do the twist: schematic of multiplexed antennas emitting coherent light with orbital angular momenta. (Courtesy: Kanté Group, UC Berkeley) A compact, integrated light source that simultaneously ...

Using the circular vibration of surface acoustic waves, a collaborative research group have successfully controlled the magnetization of a ferromagnetic thin film. Using the circular vibration of ...
