Hunting for Snarks in Quantum Mechanics
... Debate on the interpretation of quantum mechanics is centered on the meaning of the wave function ψ and ψ*ψ as probability density for particle states (Born). Broadly defined, there are two major schools: The Copenhagen school (Bohr, Heisenberg, Pauli, . . .) holds that ψ provides a complete descrip ...

Atomic orbitals and their representation: Can 3-D
... Quantum Mechanics is a non-intuitive subject. For example, the concept of orbital seems too difficult to be mastered by beginning students. Various investigations have been done on student’s difficulties in understanding basic Quantum Mechanics. Nevertheless, there are few attempts at probing how st ...

Few-body insights into the fractional quantum Hall effect
... What are quasi-particles? How many electrons make up a quasi-particle, and how do their fractional charge and unusual statistics emerge? Do properties of the non-interacting 2D free electron gas with no interactions determine whether a given filling factor yields a measurable FQHE state? ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
