Orbital angular momentum (OAM) of light is an attractive degree of freedom for fundamental studies in quantum mechanics. In addition, the discrete unbounded state-space of OAM has been used to enhance ...

Physicists have long relied on elegant theorems to connect the abstract math of quantum theory with the tangible behavior of ...

A new type of OLED can generate left- or right-handed circularly polarized light from just one form of light-emitting ...

Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

Quantum computers and communications promise more powerful machines and unbreakable codes. But to make them work, it's necessary to measure the quantum state of particles such as photons or atoms.

Unlock the mysteries of rolling motion, torque, and angular momentum in Chapter 11! Learn how rotational motion works and how it differs from linear motion. #RollingMotion #Torque #AngularMomentum #Ph ...

For the best part of 30 years physicists have been unable to answer a seemingly simple question: where does proton spin come from? As Edwin Cartlidge reports, the answer may finally be within reach ...

“What is negative global angular momentum? & How did it thwart the bull market in natural gas?” by Jim Roemer - Meteorologist ...

Diving is among the most popular spectator events in the Olympics, a graceful sport that combines elements of gymnastics and dancing. It’s also an excellent example of physics in action. Let’s look at ...

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 ...

Every dazzling jump on the ice—like Yuzuru Hanyu's quadruple Lutz at the 2017 Grand Prix of Figure Skating in Moscow, Russia—requires a mastery of balance, rotational speed and angular momentum. Aflo ...
