In a finite potential well
WebFeb 12, 2024 · Studying the particle in an infinite potential well is a pedagogical tool, allowing derivation of quantized energy levels and wave functions and demonstrating a lot of the properties of problems in QM: the solutions form an orthonormal basis, taking matrix elements, calculating "simple" problems such as time evolution etc. http://ursula.chem.yale.edu/~batista/classes/vvv/FiniteSquareWell.pdf
In a finite potential well
Did you know?
The finite potential well (also known as the finite square well) is a concept from quantum mechanics. It is an extension of the infinite potential well, in which a particle is confined to a "box", but one which has finite potential "walls". Unlike the infinite potential well, there is a probability associated with the particle … See more For the 1-dimensional case on the x-axis, the time-independent Schrödinger equation can be written as: where • $${\displaystyle \hbar ={\frac {h}{2\pi }}}$$ is … See more • Griffiths, David J.
