Researchers at the University of Maryland (UMD) have come up with a new way of optical guiding using auxiliary ultrashort laser pulses to form a ring of high-intensity light structures called “filaments.” These filaments heat the air molecules to create an extended ring of low-density heated air that surrounds a central undisturbed region, which is
When light interacts with matter, it can produce unique quasi-particles known as polaritons. These particles are half light and half matter. Polaritons have been studied by physicists for a few decades now, with researchers exploring their potential for developing highly performing lasers or other technologies.

In the field of physics, it is common to encounter different scales that can be separately described. For instance, the movement of an elephant walking in a zoo does not affect the Earth’s orbit around the sun. Similarly, the behavior of particles in materials research can be described on different scales. However, finding out which
