Advances in Physics These reviews are sometimes complemented by a "Perspectives" section which publishes shorter articles that may be controversial, with the intention of stimulating debate. The intended audience consists of physicists, materials scientists, and physical chemists working in universities, industry, and research institutes. Broad, interdisciplinary coverage includes topics ranging from condensed matter physics, statistical mechanics, quantum information, cold atoms, and soft matter physics to biophysics. The impact factor for "Advances in Physics" 18.062 in 2013, ranking it first in the discipline of condensed matter physics.

Weak interaction distances, less than the diameter of a proton. It is one of the four known fundamental interactions of nature, alongside the strong interaction, electromagnetism, and gravitation. The Standard Model of particle physics provides a uniform framework for understanding the electromagnetic, weak, and strong interactions. An interaction occurs when two particles, typically but not necessarily half-integer spin fermions, exchange integer-spin, force-carrying bosons. The fermions involved in such exchanges can be either elementary (e.g. electrons or quarks) or composite (e.g. protons or neutrons), although at the deepest levels, all weak interactions ultimately are between elementary particles. In the case of the weak
