Particle accelerators
... To reach higher and higher energies linear accelerators had to be built longer and longer. Then in 1900 Lawrence had the idea of bending the stream of electrons in a magnetic field – sort of wrapping up the accelerating electron beam.

... • Charged particles can be accelerated by an electric field. • Colliders produce head-on collisions which are much more energetic than hitting a fixed target. The center of mass energy is 2E in a collider but only m2E for a fixed target (E = energy, m = mass of the particles, E»m, c=1). • The LHC ...

... Matter behavior at the atomic nucleus scale is a fascinating subject of study. Quarks and gluons interactions are the source of their confinement in hadrons, but also of the existence of extreme states, such as those within astrophysical objects. These states can be created through ion beams produce ...

Schrödinger`s Wave Mechanical Model
... This work showed that any form of matter possesses a wavelength which is a wave property, so he proved that matter could behave like waves. However, the wave properties of matter only become significant as the form of matter becomes smaller. This work resulted in what is known as the Wave-Particle ...

7.2.4. Normal Ordering
... As in the 1st quantization case, ĵ 0 x is not non-negative so that it cannot represent the probability density of finding a particle at x. Now, we define an anti-particle as a “particle” whose attribute quantum numbers are all equal but of opposite signs to those of its particle partner. Some e ...
