General solution to the Time-independent Schrödinger equation?

In summary, the conversation discusses the search for a general solution to the time-independent Schrödinger equation in terms of the potential function V(r). The conversation includes considerations of different types of potential functions and the possibility of a non-closed form solution. There is also mention of the relationship between the TISE and the properties of the wavefunction. Overall, the likelihood of finding a usable general solution is seen as low, but the search continues.

Has anyone formulated a general solution to the time-independent Schrödinger equation in terms of the potential function V(r), and if so, what is it?

For any type of V(r).

So, instead of a differential equation, a direct relationship between the wavefunction and the potential.

Yes, I tried that first, but I couldn't find anything for, as mentioned, a general solution in terms of V(r).

And by general solution for V(r) I mean any type of V(r).

So I'm hoping some well-read physics experts here might know of it.

From the variety of approaches for different kinds of potential functions I estimate a zero probability for a (usable) general solution.
Would be something like a free lunch :cool:

The more I think about it, the less I feel qualified :H

A non-closed form solution would be really good too, hopefully there's one

From what I've seen it's the other way around: suppose we have a ##\psi## that satisfies the TISE, what are its specific properties

I believe the TISE generally produces families of discrete solutions, so a general solution would be in terms of both V(r) and parameters like quantum numbers, with the number of quantum numbers depending on the shape of V(r).

FAQ: General solution to the Time-independent Schrödinger equation?

What is the Time-independent Schrödinger equation?

The Time-independent Schrödinger equation is a fundamental equation in quantum mechanics that describes the behavior of a quantum system over time. It is a partial differential equation that relates the wave function of a system to its energy and potential.

What is the general solution to the Time-independent Schrödinger equation?

The general solution to the Time-independent Schrödinger equation is a mathematical expression that describes the wave function of a quantum system at any point in time. It is a combination of the eigenfunctions of the Hamiltonian operator, which represents the total energy of the system.

How is the Time-independent Schrödinger equation used in quantum mechanics?

The Time-independent Schrödinger equation is used to calculate the energy levels and wave functions of a quantum system. It is also used to predict the probability of a particle being in a certain position or having a certain momentum.

What are the assumptions made in the Time-independent Schrödinger equation?

The Time-independent Schrödinger equation assumes that the system is in a stationary state, meaning its properties do not change over time. It also assumes that the system is isolated and not affected by external forces.

How does the Time-independent Schrödinger equation relate to the uncertainty principle?

The Time-independent Schrödinger equation is related to the uncertainty principle in that it allows us to calculate the probability of a particle being in a certain position or having a certain momentum. This probability is inherently uncertain, as described by the uncertainty principle.
