Macroscopic Distinguishability Between Quantum States
... two ground states with different numbers N↑ and N↓ are orthogonal to each other. Since this is precisely the case in the thermodynamic limit, the fidelity between any two different ground states (in two different parameter points) is identically equal to zero. This is the famous Anderson orthogonali ...

Atomistic description of wave function localization effects in InxGa1
... In this section we analyze the electronic structure of In0.25 Ga0.75 N/GaN QWs by means of our TB model. As a model system we assume a 3.5 nm thick In0.25 Ga0.75 N/GaN QW. All QW calculations have been performed on SCs containing ≈ 82,000 atoms (≈ 10nm × 9nm × 10nm) with periodic boundary conditions ...

Quantum theory without measurement or state reduction problems
... A measurement of M with result mj prepares Q in state |mj i. However, a photon polarization measurement which destroys the photon in a photographic plate does not prepare the photon in any state, much less the one specified by the reduction postulate. Consider also a momentum measurement on a neutro ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
