Topology in optics and photonics has been a hot topic since 1890 where singularities in electromagnetic fields have been considered. The recent award of the Nobel prize for topology developments in condensed matter physics ...
Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai for Science and Technology.
The fundamental forces of physics govern the matter comprising the universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation—the particle emission from near black ...
In dark skies around the world there unfolds a nightly battle between bats and the nocturnal insects upon which they feast. You'd have thought bats, equipped as they are with echolocation, in which they navigate using sound, ...
When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic ...
The generation of high harmonics from metals opens a link between solid and plasma harmonics. High-harmonic generation (HHG) is the field of creating high-frequency photons from low-frequency lasers. HHG is the cornerstone ...
In a new publication from Opto-Electronic Advances, researchers led by Professor Andrei V. Lavrinenko and Dr. Pavel N. Melentiev from the DTU Fotonik-Department of Photonics Engineering, Technical University of Denmark, Lyngby, ...
Engineers at Duke University have devised a new approach to using sound waves to manipulate tiny particles suspended in liquid in complex ways. Dubbed a "shadow waveguide," the technique uses only two sound sources to create ...
Researchers have created and demonstrated a new vascular metamaterial that can be reconfigured to modify its thermal and electromagnetic properties.
In a new publication from Opto-Electronic Advances, Researchers led by Professor Jinghua Teng from Institute of Materials Research and Engineering, Agency for Science, Technology and Research (A*STAR), Singapore consider ...
