(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
