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 of the baryonic mass of the universe. All the power ... |

A very brief introduction to the electron correlation energy
RHF is often not accurate enough for predicting the change in energies due to a chemical reaction, no matter how big a basis set we use. The reason is the error due to the molecular orbital approximation

Jones calculus
A quaternion valued wave equation \Psi_{tt} = D^2 \Psi can be solved as usual with a d’Alembert solution \Psi(t) = \cos(D t) \Psi(0) + \sin(D t) D^{-1} \Psi'(0). We can write this more generally as e^{\beta D t} (u(0) - \beta v(0)) where \beta is a unit space quaternion where \psi(0)=u(0... |

A Derivation of Berry's Geometric Phase from the Geometric Potential
Excerpts from The Revolution of Matter
Following on from the previous derivation of the Higgs Mechanism from the Geometric Potential I'm going to show Berry's Geometric Phase is also derivable from the Geometric Potential.

Degenerate energy levels
(Redirected from Degenerate energy level)
In quantum mechanics, an energy level is degenerate if it corresponds to two or more different measurable states of a quantum system. Conversely, two or more different states of a quantum mechanical system are said to be... |

f8831a65062617ca | The Time-Energy Uncertainty Relation
John Baez
April 10, 2010
In quantum mechanics we have an uncertainty relation between position and momentum:
(Δq) (Δp) ≥ /2
Now, as you probably know, time is to energy as position is to momentum, so it's natural to hope for a similar uncertainty relation between time and energ... |
