Imaginary time is a wonky concept for our time-bound brains, but in quantum theory and mathematics, it’s a useful tool for exploring radiation's interaction with materials. A new study from scientists ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

For almost a century, physicists have been intrigued by the fundamental question: why are complex numbers so important in quantum mechanics, that is, numbers containing a component with the imaginary ...
