Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...

The membrane surrounding cells acts as a selective barrier, cradling and protecting the cell's contents from the external surroundings and choosing which substances to allow in or out of the cell.

In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum. Compared with the ...

A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally.
