An international team of researchers shows through a concrete theoretical experiment that the prediction by standard complex quantum theory cannot be expressed by its real counterpart and ratifies its ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

Ionuț Farcaș and Karen Willcox discuss how reduced-order models open new paths for simulating complex physics by compressing days of computation into seconds. In silico experimentation is the way of ...
