Your work is fine up to here:

[tex]-\frac{\hbar^2}{2m}\frac{\partial^2\psi}{\partial x^2}=E\psi[/tex]

[tex]i\hbar\frac{1}{\Theta}\frac{\partial \Theta}{\partial t}-V(t)=E[/tex]

You made a simple algebra mistake in the next step of the theta equation. Your attempts to solve the differential equations are seriously misguided. These are pretty basic differential equations. You should review how to solve them.
 

FAQ: Separation of Schrodinger Equation

What is the Schrodinger equation?

The Schrodinger equation is a fundamental equation in quantum mechanics that describes the time evolution of a quantum mechanical system. It was developed by Austrian physicist Erwin Schrodinger in 1925.

Why is separation of the Schrodinger equation important?

Separation of the Schrodinger equation is important because it allows us to solve the equation for more complex systems by breaking it down into simpler parts. This makes it easier to analyze and understand the behavior of quantum systems.

How is the Schrodinger equation separated?

The Schrodinger equation can be separated using techniques such as the separation of variables method or the perturbation theory method. These methods involve breaking down the equation into smaller, solvable parts and then combining the solutions to obtain the overall solution.

What are some applications of the separation of the Schrodinger equation?

The separation of the Schrodinger equation has many practical applications in physics, chemistry, and engineering. It is used to study the behavior of atoms, molecules, and other quantum systems, as well as to develop new technologies such as quantum computers and sensors.

Are there any limitations to the separation of the Schrodinger equation?

Yes, there are some limitations to the separation of the Schrodinger equation. It is not always possible to separate the equation for complex systems, and even when it is possible, the solutions may not accurately reflect the behavior of the system in certain situations. Additionally, the separation of the Schrodinger equation does not take into account relativistic effects, so it is not applicable in systems where these effects are significant.
