2016年4月13日 · 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 path something would follow: the equations of motion.

2016年9月29日 · Thus its role as a wave function might be somewhat questionable.But still, there must be a wave which explains the well known interference and diffraction patterns. When we see a screen illuminated by laser light that have passed through a double slit, our eyes receives photons scattered by the atoms on the surface of the screen.

2022年10月25日 · What a wave function is not is the description of a single system. All by itself a wave function also does not connect to realty. Additionally to the wave function we also have to select a preparation and a measurement operator and then we can make statements about the probabilities of events in many copies of a quantum system.

2015年6月2日 · The wave function is a function of spacetime that returns a complex number. We interpret this as meaning that the wavefunction requires two components to describe it. You can think of this as an amplitude and a phase.

2019年10月23日 · A wave function describes this wave packet. Observing a photon generally means that it has been captured (as in a CCD or on a piece of film). In being captured, the photon looses its energy to the capturing device and the wave disappears. There is nothing left for the function to describe.

Intuitively, complex conjugation of a wave function describes the time-reversed wavefunction (travelling backward in time as described by Sofia above). From a mathematical perspective; Symmetry operations in Quantum Mechanics are either deemed to be Unitary or Anti-unitary. The time reversal operator is anti unitary.

2020年12月4日 · A particle in a box has a wave function. Light in the double slit experiment has a wave function. I have a wave function, albeit an extremely complex one. When two particles interact, one can use quantum field theory to write a wave function describing the system before and after the interaction. For example, if a free electron approaches a ...

2013年10月22日 · Since the physical point of view, the wave function needs to be complex in order to explain the double-slit experiment, as well mentionated in the book of The Feynman Lectures on Physics-III, I suggest you that review chapters 1&3, where it is explained how $\psi$ has to be considered of probabilistic nature, according to the pattern of ...

2021年2月12日 · is a function whose domain is the finite index set $\{ 1, 2, \cdots, n \}$ that indexes the dimensions of the space. This function is exactly the analogue of the wave function in the ket case, only here, the "index of dimensions" is a point in space , so that there now are as many dimensions as there are points in space , and we need to add up ...

2017年5月18日 · In this sense the complex conjugate square of the wave function that gives the probability for an event to happen, is physical. It is a real number and accumulating measurements with the same conditions always gives the same probability distribution, even though there are levels upon levels of modeling.
