Despite decades of study, black holes are still among the most powerful and mysterious celestial objects ever studied. Because of the extreme gravitational forces involved, nothing can escape the surface of a black hole (including ...
Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research ...
Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. Because the new correlator is faster than other methods and works with a wide range of radio frequency ...
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast ...
Two-photon microscopy (TPM) enables the observation of cellular and subcellular dynamics and functions in deep nervous tissues, providing critical in situ and in vivo information for understanding neurological mechanisms.
A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material.
Researchers including a postdoc at the University of Massachusetts Amherst have created a gear-shaped photonic crystal microring that increases the strength of light-matter interactions without sacrificing optical quality. ...
Together with their colleague Professor Stefano Longhi (Polytechnic Institute of Milan), physicists from the group of Professor Alexander Szameit (University of Rostock) have discovered a triple phase transition. At the critical ...
Recently, a research team from Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) has proposed a new method of using surface mode (SM) coupling to adjust the thermal coefficient ...
Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concepts of metasurface and metamaterials have proven fruitful results in the realm of meta-optics. Previous research attentions ...
