![]() ![]() DIET is also closely related to another phenomenon, called electromagnetically-induced transparency (EIT). The scientists explain that, on the most basic level, DIET results from destructive interference between the electromagnetic waves emitted by the quantum emitters. In particular, the medium may become transparent at a particular frequency that can be controlled to a certain extent. Here, the researchers have theoretically shown that strong dipole-dipole interactions in a dense vapor of quantum emitters can be used to manipulate the spectral properties of the light scattered by the emitters. The collective effects usually result in an enhancement of the light-matter interaction, although a very complicated one. In a dense "vapor" of many quantum emitters, strong dipole-dipole couplings can then occur. In this case, the electromagnetic field experienced by an emitter depends not only on the light beam striking its surface, but also on all of the electromagnetic fields radiated by all of its neighbors, which in turn are affected by the emitter in question.Įach quantum emitter can have a dipole, meaning a positive side and a negative side, due to an uneven distribution of electrons within the emitter. But the physics becomes much more complex when dealing with two or more interacting emitters. "We showed how light scattering by a nanometric size system, collectively responding through strongly coupled two-level atoms/molecules, can be manipulated by altering the material parameters: an otherwise opaque medium can be rendered transparent at any given frequency, by adequately adjusting the relative densities of the atoms/molecules composing it."Īs the scientists explain, light scattering is very well understood when dealing with individual quantum emitters that is, single atoms or molecules. "The significance of our work is in the discovery of a very neat phenomenon (dipole-induced electromagnetic transparency ), which may be used to control light propagation in optically active media," coauthor Eric Charron, Professor at the University of Paris-Sud in Orsay, France, told. This ability could have several potential applications, such as producing slow light or stopped light, along with applications in the field of attosecond physics. They theoretically show how to induce transparency in otherwise opaque materials using the complex dipole-dipole interactions present in a large number of interacting quantum emitters, such as atoms or molecules. Send us feedback about these examples.In a new study published in Physical Review Letters, researchers have developed a new method for manipulating light scattering. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'translucent.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2023 Another perk of this powder was the variety of shades - six, ranging from translucent to deep - to provide a better match for more skin tones over making just one translucent shade. 2023 Its lightweight, translucent formula is key to a matte, polished look that lasts all day. Robert Lloyd, Los Angeles Times, 22 Nov. 2023 As in the series, contestants are housed in a giant dormitory, over which hangs a big translucent sphere filled with money (and more money as contestants go home). ![]() Lois Ellen Frank and Walter Whitewater, Saveur, 22 Nov. 2023 Add the onions and cook, stirring occasionally, until translucent, about 3 minutes. Lisa Cericola, Southern Living, 22 Nov. 2023 Reduce heat to medium add onion to skillet, and cook until translucent, about 2 minutes. Andrea Wurzburger, Better Homes & Gardens, 13 Oct. 2023 The sheets were lightweight and nearly translucent when held up to the light. Jasmine Smith, Southern Living, 13 Oct. 2023 Add onion and garlic cook, stirring occasionally, until onion is translucent, about 5 minutes. Recent Examples on the Web From 1949, when his early figurative pictures finally liquefied into stains of translucent color, Rothko painted with no allusions, no particulars.
