Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be ...

Changing gears changes the size of the cog; the smaller the cog the more revolutions of the back wheel you get per ...

Quantum entanglement, a phenomenon studied by Einstein, Podolsky, and Rosen in 1935, challenges our classical understanding of physics. It allows two particles to remain connected regardless of ...

When a star is born, it doesn’t emerge in isolation. Instead, it forms inside a large, chaotic cloud of gas and dust. Around it, a flat disk of spinning material takes shape. This protoplanetary disk ...

Swinging arms while walking stabilizes torso, conserves energy, and enhances efficiency by utilizing angular momentum principle.

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 ...

The research is published in Science Advances. In a peculiar twist, the researchers found that their orbital angular momentum-carrying beam of light grows in a mathematically recognizable pattern ...

The multiplexing/demultiplexing module fabricated (a,d) employs a property of light called the "optical vortex" to transmit/receive multiple signals simultaneously ...
