@mfb oh thank you , I think now I understand what I miss, It's time invariance...

@Phy_enthusiast I know that, it's not my point. @mfb Can you please show in more detail how the underling Hamiltonian will still be time invariant? that what I can't figure out!

Hi, I raised this question in another forum but get no satisfactory answer, so hope will get something new here... Stationary orbits of atoms are based on variable separation (time and spatial) of usual Schrodinger equation when Hamiltonian is time independent, and we get eigenvalues for...

Homework Statement find Transmission and Reflection coefficients (QM) for the following triangular potential well: U=U_{0}(1-\frac{x}{a}) : x\geq0 and U= 0 : x<0 and U_{0}>0 , a>0 Homework Equations The Attempt at a Solution Basically constructing the wave functions is...

I understand that you are talking about dipoles , but I mean if we imagine abstract empty universe with just one charged particle...

Did you forget Energy-Momentum Tensor and Energy flux? in electromagnetic field description there is kind of different rates of energy flaw in different directions, and this can be thought as a kind of "energy direction", anyway this flaw should be transformed in a tricky way (i.e Lorentz...

Hi All A question that bothering me and I can't find answer for: a charged particle in empty space will generate an electromagnetic field that has energy density and can be described by Energy-Momentum Tensor. A non charged particle at rest also has energy due to mass energy...

Thank you for the detailed answer :) I checked Hong–Ou–Mandel effect on wikipedia and "Stimulated emission of two photons in parametric amplification and its interpretation as multi-photon interference" paper from arXiv, now it's much clearer how interference of indistinguishable photons plays...

from the beginning, my question was crystal clear, and i tried a lot to avoid a side discussions, so I suggest closing it, becuase I got my answer long time ago, and which is: No, none of the mathematicians can read and understand purely formal math books without any other help/sources...

Yes I agree with you, that sentence seems to be very suspicious. Can you please point out to some book to read more about this matter? becuase I couldn't find anything else on this matter on Internet (even wikipedia), and the most books of general course of atomic physics gives it as an axiom...

Hi All I was surfing Internet trying to understand why most books i read simply considers that the stimulated photon emission has same properties as the stimulating photon, and treats this simply as an "take as it is". For my surprise, i found this article...

Dear simplicity123, I don't know from where to start becuase we already discussed most of what you said. First of all once i spent a complete year trying to visualize linear algebra's highly formal book of 300 pages becuase i hadn't any other choices, even Internet or teacher. Secondly I'm...

If you noticed the title of the post was if mathematicians understand their books, and all of the repliers including yourself stated that they still need intuition, the aim of the question for the first place was to understand if there is some people that can think completely formally without...

Sorry to say that but it is completely misleading, that means that all books & teachers are good, but we are stupid and can't understand them, and you lost in your words two main points: +Time: why i should spend couple days to find the best book? if you can't write for "humans" so don't. +The...

No this why it's an author's problem, not reader's, he should gather this different point of views and light up the differences between them to raise up the reader's awareness, instead of wasting our time!
