Does the Hamiltonian always translate to the energy of a system? What about in QM? So by the Schrodinger equation, is it true then that $i\hbar{\partial\over\partial t}|\psi\rangle=H|\psi\rangle$ means that $i\hbar{\partial\over\partial t}$ is also an energy operator? How can we interpret this? Thanks.

Sabine Hossenfelder believes that
Schrödinger meets Newton.
But is the story about the two physicists' encounter true?
Yes, these were just jokes. I don't think that Sabine Hossenfelder misunderstands the history in this way. Instead, what she completely misunderstands is the phys... |

If you want to win a Nobel Prize in Physics by finding the unified field theory, it’s pretty obvious that you will have to learn how to make Quantum field theory (QFT) calculations. In the 1940s, Richard Feynman and Ernest Stueckelberg independently developed a notation (now kn... |

Quantum gravity researcher at work.
We normally think about geometry as distances between points. The shape of a surface is encoded in the distances between the points on in. If the set of points is discrete, then this description has a limited resolution.
But there’s a dif... |

Consider Schrödinger's time-independent equation $$ -\frac{\hbar^2}{2m}\nabla^2\psi+V\psi=E\psi. $$ In typical examples, the potential $V(x)$ has discontinuities, called potential jumps.
Outside these discontinuities of the potenti... |

6a50edeec594a1e1 | Schrödinger's equation — what is it?
Marianne Freiberger
Here is a typical textbook question. Your car has run out of petrol. With how much force do you need to push it to accelerate it to a given speed?
The answer comes from Newton’s second law of motion:
\[ F=ma, \]
where $a$ is acceleration, $F$ is force ... |
