  1. quantum mechanics - What is a wave function in simple language ...

    Apr 13, 2016 · The wave function is the solution to the Schrödinger equation, given your experimental situation. With a classical system and Newton's equation, you would obtain a trajectory, showing the …

  2. What is the meaning of the wavefunction? - Physics Stack Exchange

    Oct 25, 2022 · Now you might find all this a little unsatisfactory because it still doesn't tell you what the wave function means or that its square modulus is a probability density. But it at least helps to give …

  3. What is the unit (dimension) of the 3-dimensional position space ...

    Aug 3, 2017 · The wave function of an electron does not signify anything in itself. The only useful thing we can get from it is the probability density (probability per unit volume), which is the square of its …

  4. Writing wave functions with spin of a system of particles

    And this is a symmetric configuration for the spin part of the wave function. So this is coherent. But, for an other physical problem, with fermions,you may have to minimize another kind of energy, which …

  5. Practically, how does an 'observer' collapse a wave function?

    Oct 23, 2019 · The wave function is the probability amplitude (see this post) which is not the same thing as a probability density (also called a distribution, the thing you normally encounter in your basic …

  6. quantum mechanics - Differences between wavefunction, probability …

    You should compare this to a pressure and pressure density or to mass and mass density. The relation between the quantum wave function and probability density is given by the Born rule which is …

  7. What equation describes the wavefunction of a single photon?

    Sep 29, 2016 · You can also say that the wavefunction of a photon is defined as long as the photon is not emitted or absorbed. The wavefunction of a single photons is used in single-photon …

  8. quantum mechanics - Why does observation collapse the wave …

    In von Neuman interpretation the collapse of the wave function happens when the observer feels any qualia (feeling) depended on the measured value. In Bohm interpretation the collapse of the wave …

  9. What is the position wavefunction of coherent states?

    Sep 22, 2020 · One is defined by the quadratures as in your answer, the other is physical space arising from the plane wave dependence of the creation operators when transferring to position space.

  10. quantum mechanics - Is the wavefunction a physical wave or only a ...

    May 19, 2017 · In summary, the debate is about whether the wavefunction is a real physical wave as the psi-ontologists claim, or simply a mathematical abstraction that provides information in the form of …
