For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain ...

Non-perturbative interactions (i.e., interactions too strong to be described by so-called perturbation theory) between light and matter have been the topic of numerous research studies. Yet the role ...

Since the origins of the mathematical knot theory, development of which was prompted by early attempts of understanding structure of atoms, knotted fields and vortices arise in superstring and quantum ...
