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... |

For the component in an internal combustion engine, see Crankcase ventilation system.
In physics, a breather is a nonlinear wave in which energy concentrates in a localized and oscillatory fashion. This contradicts with the expectations derived from the... |

Without having looked into Achim's work in detail, I wonder: how does it relate to Connes' reconstruction theorem, which proves that a Riemannian manifold c... |

In the physical sciences, the Airy function (or Airy function of the first kind) Ai(x) is a special function named after the British astronomer George Biddell Airy (1801–1892). The function Ai(x) and the related function Bi(x), are ... |

Atom lasers
06 Aug 1999
The exotic quantum phenomenon of Bose–Einstein condensation is the key ingredient in a new type of laser that emits atoms rather than photons, and that promises to revolutionize atom optics
Soon after the invention of the laser in the late 1950s many dubbed the discover... |

LOG#249. Basic twistor theory.
This my last normal post. Welcome to those who read me. TSOR is ending and from its ashes will arise another project. That is inevitable. I want to use new TeX packages, and that is not easy here, to simplify things, and to write better things I wish to tell the world.... |

Double-donor complex in vertically coupled quantum dots in a threading magnetic field
We consider a model of hydrogen-like artificial molecule formed by two vertically coupled quantum dots in the shape of axially symmetrical thin layers with on-axis single donor impurity in each of them and with... |

See also: Molecular orbital.
In chemistry, molecular orbital theory (MO theory or MOT) is a method for describing the electronic structure of molecules using quantum mechanics. It was proposed early in the 20th century.
In molecular orbital theory, electrons in a molecule are not a... |

"This is evidently a discovery of a new particle. If anybody claims otherwise you can tell them they have lost connection with reality." -Tommaso Dorigo

Classical objects push and pull in tangible and deterministic gestures. A Newton's cradle collides on one side, energy courses through the system, and it erupts on the other side. Quantum objects mystify the imagination with erratic and unpredictable behavior. Psi guides the listener from a c... |
158f8557388166e3 | Exciton dynamics
Excitons are electron-hole pairs bound by Coulomb interaction which can be generated in semiconductors or insulators by interaction with light. In the simplest case, they involve excitations of electrons from the (highest) occupied to the (lowest) unoccupied molecular orbital, or from valence to condu... |
