  2. Azimuthal quantum number - Wikipedia

    en.wikipedia.org/wiki/Azimuthal_quantum_number

    The term "azimuthal quantum number" was introduced by Arnold Sommerfeld in 1915 [1]: II:132 as part of an ad hoc description of the energy structure of atomic spectra. . Only later with the quantum model of the atom was it understood that this number, ℓ, arises from quantization of orbital angular moment

  3. Quantum number - Wikipedia

    en.wikipedia.org/wiki/Quantum_number

    In the era of the old quantum theory, starting from Max Planck's proposal of quanta in his model of blackbody radiation (1900) and Albert Einstein's adaptation of the concept to explain the photoelectric effect (1905), and until Erwin Schrödinger published his eigenfunction equation in 1926, [1] the concept behind quantum numbers developed based on atomic spectroscopy and theories from ...

    Now consider =, i.e. the field oscillates at the same rate the dipole exposed to the field does. That is a case of resonance.Then at specific points in time, namely = (+) +, the dipole will flip, going to the other energy eigenstate [] with a 100% probability.

    Yang Chen-Ning or Chen-Ning Yang (simplified Chinese: 杨振宁; traditional Chinese: 楊振寧; pinyin: Yáng Zhènníng; born 1 October 1922), [1] also known as C. N. Yang or by the English name Frank Yang, [2] is a Chinese theoretical physicist who made significant contributions to statistical mechanics, integrable systems, gauge theory, and ...

  7. Principal quantum number - Wikipedia

    en.wikipedia.org/wiki/Principal_quantum_number

    In quantum mechanics, the principal quantum number (n) of an electron in an atom tells which electron shell it's in. Its values are natural numbers (1, 2, 3, ...). This number tells the energy level of electrons in that shell (although there's other factors).

  8. Quantum circuit - Wikipedia

    en.wikipedia.org/wiki/Quantum_circuit

    The quantum logic gates are reversible unitary transformations on at least one qubit. Multiple qubits taken together are referred to as quantum registers.To define quantum gates, we first need to specify the quantum replacement of an n-bit datum.

  9. Quantum mechanics - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics

    Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
