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 ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Subscribe to our newsletter for the latest ...

A newly-detected spinning galaxy filament is reshaping our understanding of cosmic structure, gas flows, and the origins of galactic spin.

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.

Take a look out there at the Universe, and while the stars might give off the light that you'll first notice, a deeper look shows that there's much more out there. The brightest, most massive stars, ...

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 ...

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 ...

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

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 research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...
