Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

Quantum jump of an electron
To answer it simply, electrons can only orbit in certain energy shells (these "orbits" are not at all like a classical orbit {they can really be considered the state vectors of a harmonic oscillator's …

Quantum jump of an electron
The electron cannot fall to lower than its original state because all energy levels below it are filled (the Pauli Exclusion Principle limits the amount of electrons per shell)
To explain
Scenario …

Momentum in a quantum particle in a box
The momentum operator in one dimensional quantum mechanics is:
$$\hat p_x=\frac{\hbar}{i}\frac{d}{dx} $$ and we can imagine creating an eigenvalue-eigenfunction system $$\hat p_x\psi = p_x\psi.$$
As a …

Creation and annihilation operators in the hydrogen atom
In my quantum chemistry course, we have been discussing the wavefunctions of the hydrogen atom, further, I am familiar with the idea of ladder operators from the quantum harmonic oscillator. Can we us …
