Definition/Meaning | Word/Phrase |
---|---|

(physics) a theory of atomic structure that combined Rutherford's model with the quantum theory; electrons orbiting a nucleus can only be in certain stationary energy states and light is emitted when electrons jump from one energy state to another | Bohr theory |

British nuclear physicist (born in Germany) honored for his contributions to quantum mechanics (1882-1970) | Born , Max Born |

English theoretical physicist who applied relativity theory to quantum mechanics and predicted the existence of antimatter and the positron (1902-1984) | Dirac , Paul Adrien Maurice Dirac |

no two electrons or protons or neutrons in a given system can be in states characterized by the same set of quantum numbers | exclusion principle , Pauli exclusion principle |

United States chemist (born in Poland) who used quantum mechanics to understand chemical reactions (born in 1937) | Hoffmann , Roald Hoffmann |

(quantum theory) the theory that it is impossible to measure both energy and time (or position and momentum) completely accurately at the same time | indeterminacy principle , uncertainty principle |

German physicist whose explanation of blackbody radiation in the context of quantized energy emissions initiated quantum theory (1858-1947) | Max Karl Ernst Ludwig Planck , Max Planck , Planck |

quantum of electromagnetic radiation; an elementary particle that is its own antiparticle | photon |

(physics) the basis of quantum theory; the energy of electromagnetic waves is contained in indivisible quanta that have to be radiated or absorbed as a whole; the magnitude is proportional to frequency where the constant of proportionality is give by Plan | Planck's law |

relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons | QED , quantum electrodynamics |

act of dividing into quanta or expressing in terms of quantum theory | quantisation , quantization |

(physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory) | quantum |

discrete amount of something that is analogous to the quantum in quantum theory | quantum |

branch of quantum physics that is concerned with the theory of fields; it was motivated by the question of how an atom radiates light as its electrons jump from excited states | quantum field theory |

(physics) an abrupt transition of an electron or atom or molecule from one quantum state to another with the emission or absorption of a quantum | quantum jump |

branch of quantum physics that accounts for matter at the atomic level; an extension of statistical mechanics based on quantum theory (especially the Pauli exclusion principle) | quantum mechanics |

branch of physics based on quantum theory | quantum physics |

quantum of energy (in a crystal lattice or other system) that has position and momentum and can in some respects be regarded as a particle | quasiparticle |

(physics) a quantum of energy or quasiparticle that can be propagated as a traveling wave in nonlinear systems and is neither preceded nor followed by another such disturbance; does not obey the superposition principle and does not dissipate | solitary wave , soliton , soliton wave |

modern form of quantum theory; an extension of quantum mechanics based on Schrodinger's equation; atomic events are explained as interactions between particle waves | wave mechanics |
