Have known a wave function, how get does distributing density function of the probability?
The discussion revolves around the probability density function of a wave function in quantum mechanics, specifically how to derive it from a given wave function and its relation to energy. Participants explore the mathematical expressions involved and the implications of their formulations.
The discussion contains multiple competing views, particularly regarding the validity of the proposed formula and the understanding of quantum mechanics concepts. No consensus is reached on these points.
Participants express uncertainty about the definitions and implications of various terms and concepts, indicating a potential gap in foundational knowledge that affects the clarity of the discussion.
Individuals interested in quantum mechanics, mathematical formulations in physics, and the interplay between information theory and quantum statistics may find this discussion relevant.
<br /> <br /> I want to know the relation between \mathbb{P} and energy.<br /> And formula of underneath in:<br /> <br /> \newcommand{\pd}[2]{\mathbb{P}({#1},{#2})}<br /> \mathbb{I}=\idotsint \frac {\pd {\vec{r}} {t}} {\pd {\vec{r}_m} {t_m}} \cdot (1-ln(\frac {\pd {\vec{r}} {t}} {\pd {\vec{r}_m} {t_m}})) \,D \vec{r} \,dt<br /><br /> <br /> Among them, \mathbb{P}(\vec{r},t) at \vec{r}= {\vec{r}}_m and t= t_m take the biggest value.<br /> <br /> Is the relation between \mathbb{I} and energy the inverse ratio relation?dextercioby said:You mean,if you have \Psi(\vec{r},t) [/tex],how does one get probablility density...?<br /> Simple:<br /> \mathbb{P}=:|\Psi (\vec{r},t)|^{2}<br /> <br /> Daniel.<br /> <br /> <br /> P.S.Or was the question about something else...?<img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":confused:" title="Confused :confused:" data-smilie="5"data-shortname=":confused:" />
dextercioby said:I've never seen your formula...Is it somehow linked to quantum statistics...?In quantum statistics,we don't use Dirac's description of quantum states,but rather von Neumann's...
Please give more details.

dextercioby said:You mean the fluctuation.Fluctuation in what...?That would account for it.What do you mean you created it...?
Did u study QM or SM...?If not,that would explain why u never heard of John von Neumann and why your formula has 99.99% chances of being incorrect.
Daniel.
Perhaps I do not have what you study deep, but I am study QM and MATH and computer.dextercioby said:I've already told you,that is other Neumann.This quy has nothing to do with QM and QSM...
Daniel.
I don't knew what you say.I don't read understand.I am sorry.dextercioby said:Nope,that guy is a German.John von Neumann was a Hungary-born American.Mathematician,the one which axiomatized and mathematically founded Quantum Mechanics and Quantum Statistics...
