Researchers in the US have taken images of individual atoms in an ultracold fermionic gas as it makes the transition from a metallic phase to a band insulator and then to a Mott insulator. This is the first study of such a transition in a fermionic gas to be made with single-site and single-particle resolution. While such experiments are routinely done using ultracold bosonic atoms, doing the same with fermions is more challenging because they are difficult to cool. However, the rewards for physicists could be greater because fermionic atoms are a closer match to electrons in a solid, and therefore such experiments could shed light on poorly understood solid systems such as high-temperature superconductors.  A new scientific instrument at the Department of Energy's SLAC National Accelerator Laboratory promises to capture some of nature's speediest processes. It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules that take place in less than a tenth of a trillionth of a second – information that will benefit groundbreaking research in materials science, chemistry and biology.  As an elementary particle, the electron cannot be broken down into smaller particles, at least as far as is currently known. However, in a phenomenon called electron fractionalization, in certain materials an electron can be broken down into smaller "charge pulses," each of which carries a fraction of the electron's charge. Although electron fractionalization has many interesting implications, its origins are not well understood.  New ideas for interactions and particles: This paper examines the possibility to origin the Spontaneously Broken Symmetries from the Planck Distribution Law. This way we get a Unification of the Strong, Electromagnetic, and Weak Interactions from the interference occurrences of oscillators. Understanding that the relativistic mass change is the result of the magnetic induction we arrive to the conclusion that the Gravitational Force is also based on the electromagnetic forces, getting a Unified Relativistic Quantum Theory of all 4 Interactions.
