Definition of quantum mechanics in English:

quantum mechanics

plural noun
Physics
  • treated as singular The branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles, incorporating the concepts of quantization of energy, wave–particle duality, the uncertainty principle, and the correspondence principle.

    〔物理〕量子力学

    Example sentencesExamples
    • His official courses were on quantum mechanics, classical mechanics, and complex function theory.
    • Even a biologist must trust what a physicist says about quantum mechanics.
    • His interests range from astrophysics and quantum mechanics to mathematical puzzles and games.
    • The theory that describes atoms and their constituents is quantum mechanics.
    • String theory's claim thus allows quantum mechanics to incorporate gravity and do so successfully.
    • One of the bizarre paradoxes of quantum mechanics is that elementary particles can exist in two or more states at the same time.
    • According to the laws of quantum mechanics, these electrons may exist only in certain states.
    • On the other hand, in quantum mechanics you will deal more with algebraic techniques.
    • For Doppler cooling, we need another detail from quantum mechanics, and a bit of relativity.
    • It can be said that Heisenberg's quantum mechanics has made possible a systemization of spectra of atoms.
    • In the answer to this question lies the whole key to quantum mechanics.
    • In fact, it is arguably the most important fundamental concept behind all of quantum mechanics.
    • So with growing trepidation, I searched through my past writings on quantum mechanics.
    • We know from quantum mechanics that nothing is real, except for the observations themselves.
    • What happens when we add quantum mechanics to the analysis of classical black holes?
    • This implies that we will always have uncertainty in any system, not just in quantum mechanics or in mathematics.
    • The entire field of quantum mechanics owes much of its existence to the study of angular momentum.
    • The second question, of course, was rendered questionable by quantum mechanics.
    • In 1976 I began investigating what quantum mechanics might have to say.
    • Firstly, it consistently embodies both special relativity and quantum mechanics.

Derivatives

  • quantum-mechanical

  • adjective
    Physics
    • However, as a subatomic particle the electron is also a quantum-mechanical object.
      Example sentencesExamples
      • Being quantum-mechanical, the electron can also be in a ‘superposition’ of these states, pointing both up and down at the same time.
      • In other words, its quantum-mechanical wavefunction remains unchanged when viewed in a mirror.
      • The origin of this destructive phenomenon is a quantum-mechanical interaction between the spins of the electrons and the atomic magnetic moments.
      • No prize had been awarded in physics since 1930, yet recent theoretical and experimental achievements had led to a revolutionary new quantum-mechanical depiction of the atom.
      • Furthermore, experiments are insensitive to the overall phase of quantum-mechanical wavefunctions - a property known as gauge invariance - which leads to the conservation of electric charge.
