Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to ...

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

The orbital angular momentum states of light have been used to relate quantum uncertainty to wave–particle duality. The ...

Theoretical physicists along with an experimental team have found evidence of a quantum spin liquid in a material known as pyrochlore cerium stannate. They achieved this by combining state-of-the-art ...

A research team led by Dominik Schneble, Ph.D., Professor in the Department of Physics ... matter waves. In contrast, conventional processes emit photons traveling at the speed of light.
