Sir Chandrasekhara Venkata Raman and his student Nagendra Nath published a series of papers in 1936 on the diffraction of light by a liquid in the field of a high frequency sound wave. This was ...

First experimental observation of matter-wave diffraction in a short-lived electronpositron atom using a graphene-based ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Advancements in quantum imaging are transforming scientific research, offering unprecedented resolution and sensitivity for ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...
