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.

Why does the power series method result in discrete levels of energy in the case of the quan...
Working my way through Griffiths' "Introduction to Quantum Mechanics", I found the following excerpt:
The result is the same as what I'd gotten using the operators' method, and yet in this context, i …

A question about the general solution to the infinite square well
I was working through Griffiths' Introduction to Quantum Mechanics, specifically the part about the 1D infinite square well potential (situated between $x = 0$ and $x = a$). To my understanding, this …

A question about the general solution to the infinite square well
I have now understood that the general solution is not simply a sum of the stationary states, but rather a LINEAR COMBINATION of the stationary states, thus the presence of the $C_n$'s.
I also underst …
