A team of researchers at Utrecht University, the Norwegian University of Science and Technology and the University of Konstanz has recently proposed a new method to determine magnon coherence in solid-state devices. Their ...
Researchers at Weizmann Institute of Science and Cinvestav recently carried out a study testing the theory of Hawking radiation on laboratory analogues of black holes. In their experiments, they used light pulses in nonlinear ...
Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. The different colors are emitted from different parts of the quantum dot—red from the core, green from ...
(Phys.org)—Physicists have demonstrated that two independently developed concepts—quantum coherence and the nonclassicality of light—both arise from the same underlying resources. The ability to explain seemingly distinct ...
(Phys.org) —All objects' colors are determined by the way that light scatters off of them. By manipulating the light scattering, scientists can control the wavelengths at which light is transmitted and reflected by objects, ...
(Phys.org) —In a well-known quantum effect called superradiance, atoms can emit light at an enhanced rate compared to what is possible in classical situations. This high emission rate arises from the way that the atoms ...
(Phys.org) —Last week saw the physics community buzzing as a physicist suggested that the speed of light might be slower than thought—James Franson of the University of Maryland posted an article in a peer-review journal ...
Carbon nanotubes have the potential to function as light-emitting devices, which could lead to a variety of nanophotonics applications. However, nanotubes currently have a low luminescence quantum yield, typically around ...
(Phys.org) —By their very nature, unstable particles will eventually decay, some faster than others. But according to the quantum Zeno paradox (QZP), an unstable particle that is observed continuously has been said to never ...
(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the ...
