High Energy Physics

Particle physics is one of the branch of physics that studies the fundamental building blocks of matter and the forces as well as the interactions between them. It is also commonly called High Energy Physics (HEP) since in most cases these fundamental particles need special high energetic circumstances to create and study them. There are two such accelerators; hadron colliders and electron-positron-colliders. The progress in particle physics has been done both experimentally and theoretically.

The best theoretical model that explains the nature well upto high precision is known as the Standard Model (SM) which is however an effective low energy realization of a more fundamental theory. The SM deals at the microscopic scale with the properties of the fundamental particles and the forces mediated by gauge bosons involved in the interactions among them. There are four fundamental forces known in nature; electromagnetic, weak, strong, and the gravity and the SM unifies three of these except the gravity. The SM is considered the pillars of the fundamental physics and in 1979 Sheldon Glashow, Abdus Salam and Steven Weinberg won the Nobel prize for formulating the framework.
With the discovery of the Higgs boson in July 4, 2012 at the Large Hadron Collider at CERN near Geneva, Switzerland, the Standard Model has been finally concluded. Since the SM is an effective theory, pursuing the form of the physics beyond the SM has been continuing for more than three decays with no experimental clue so far. The weakness of the SM boils down to three things: (1) the Dark matter, (2) naturalness issue and (3) origin of neutrino mass. As a remedy to these issues, there are very popular scenarios like supersymmetry, extra dimensions etc. Final word about the type of physics beyond the SM will be said by experiments like Large Hadron collider and the excitement is still running very high in the community.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Scientists Discover New “Hall Effect” That Could Revolutionize Electronics

Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices . A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices . Their study, published in Physical Review Letters, was conducted in collaboration with graduate student Bastián Pradenas and Professor Oleg Tchernyshyov of Johns Hopkins University. The researchers uncovered evidence of a new property, dubbed the “Hall mass,” in a class of complex magnetic materials known as noncollinear antiferromagnets . The traditional Hall effect, discovered by Edwin Hall at Johns Hopkins in 1879, describes how an electric current is deflected sideways when subjected to an external magnetic field, generating a measurable voltage. This effect plays a crucial role in technologi...
