Semicircular potential well
In quantum mechanics, the case of a particle in a one-dimensional ring is similar to the particle in a box. The particle follows the path of a semicircle from 0 to pi where it cannot escape, because the potential from pi to 2 pi is infinite. Instead there is tot... |
1b74f10145dff53d | There is no doubt that quantum theory has been remarkably successful and has passed every experimental test it has been subject to. But the interpretation of quantum theory - in particular the meaning of the wavefunction, the role of observers, and the question of what happens to the state of a system during a measurem... |

I'm reading the Wikipedia page for the Dirac equation:
The Dirac equation is superficially similar to the Schrödinger equation for a free massive particle:
A) $-\frac{\hbar^2}{2m}\nabla^2\phi = i\hbar\frac{\partial}{\partial t}\phi.$
The left side represents the square of the momentum operator divide... |

Physical Quantum Mechanics 9: Big Lie More Convincing
In this sequence we argue that a second order real-valued form of Schrödinger's equation:
• $\ddot\psi + H^2\psi =0$ (1)
may be to prefer before the standard first order complex-valued form:
• $i\dot\psi + H\psi =0$, (... |

I don't really know much about Quantum mechanics, but would like to know one simple fact.
The state function $\Psi(r, t)$ whose magnitude gives the probability density of the position of the particle and the magnitude of its ($\Psi(r, t)$) fourier transform gives probability density of its momentum. Is ther... |

Quantum mechanics: Suppose that there is a particle with orbital angular momentum |L|. But if the particle also has spin quantity |S| the question is: How do I reflect this into Schrodinger equation? I do know how Schrodinger equation becomes for each case - when a particle has particular orbital angular mom... |

You know how there are no antiparticles for the Schrödinger equation, I've been pushing around the equation and have found a solution that seems to indicate there are - I've probably missed something obvious, so please read on and tell me the error of my ways...
