I began my physics study about one year ago and learned all of classical mechanics in that year; but I am now studying Quantum Mechanics. The book I'm using (Dirac's Principles of Quantum Mechanics) Introduces Bra-Ket notation in the first chapter rather concisely. I understand the mathemati...

In quantum mechanics, it is common practice to write down kets which have infinite norm, i.e. non-normalisable wavefunctions. Examples include states whose wavefunctions are Dirac delta functions or infinite plane waves. These do not, technically, belong to the Hilbert space itself. However, ...
I'll move on, maybe in future we will discuss this. Right now I'm doing qm from McIntyre so skipping this subtle aspect is alright. Likes vanhees71 Apr 1, 2022 #14 Kashmir 466 74 vanhees71 said: There are no simple operators for angles in quantum mechanics. That's why the ...
内容提示: 1 Bra-ket notation In quantum mechanics, Bra-ket notation is a standard notation for describing quantum states, composed of angle brackets and vertical bars. It can also be used to denote abstract vectors and linear functionals in mathematics. It is so called because the inner ...

Unlike classical mechanic that deals with things on a large scale, quantum mechanic is on a quantum scale and it is probabilistic due to some uncertainty.Answer and Explanation: When you're solving some problems in quantum mechanics, you may have an encounter with the Bra-Ket notation. A ...
For example, in some interpretations of quantum mechanics (such as the many-worlds interpretation) the ket vector associated to the system state is said to correspond to an element of physical reality, while in other interpretations it is not. 例如在某些量子力学的诠释中(比如多世界诠释),表示系...
