Quantum Theory

1) I know that light exhibits wave/particle duality. 2) I know that pretty much all fundamental particles exhibit the same kind of duality where the "wave" is a region of probability where the particle might exist. Conclusion: the "wave" property of light is the same region of probability for the photon. Not exactly a deductive argument, but am I right?

i understood Qm in 1d well but i started to study in 3d just a day ago and i have some questions. first of all quantum numbers and there are several polynomial functions such as Bessel. so i cant understand them so well . they are a little complicated and David Griffith who is the author of the book that i am studying did not explain them detailed. by the way i don't know electromagnetism well and i think the problem occurs cause of this but i don't want to spend time to learn that subject from beginning so what do you suggest to me. i am looking for your responds.

Okay, how does a electron absorb a photon? Can anyone explain this to me, or is it one of those things in physics that can't be broken down into laymens terms? Or is their even a mathematical explanation of this phenomena?

Does the same explanation for the interaction between charged particles, that QED offers, apply to the magnetic field? Is the magnetic field explained as the overlapping of virtual particles.

So according to Quantum Theory, if light consists of a photon then photon will be the smallest particle towhich human can observed because human eye can see any thing if a light rays get reflected from any object or matter

Can you give me references, if any, to the justification of adiabatic hypothesis in QFT? Why should we switch off the interaction in asymptotic states? Because we cannot solve coupled equations?

I believe all electromagnetic radiation is comprised of photons. Is there any experimental evidence that radio transmitters emit photons rather than continuous em waves?

I have been writing a paper on Einstiens theory of relativity for grouped particles. My background is electrical engineering and Math. I have a need for some in depth physics help to prove a few things. I have been able to prove that space does not exist at the speed of light from our point of view and time dialation is a vector and varies at different rates tangentially versus congruently to the direction of propagation. I have also been able to prove that relativity does not apply to circular motion. This with some other findings have led me to some theories on the photon and it's associated field. If I am correct the photon is a particle and the associated wave is…

Whats the difference.... I have two examples where it is used most often. 1) The very early universe consisted of Pure Energy. 2) Matter and anti-matter anihilate each other into Pure Energy.

Hi, Was wondering, if and how tunneling is apparent with-in the suns core - the nuclear fusion.

So, I did get from another thread that it's not possible to use quantum entanglement for superluminal communication. However, here's a layman-oriented article describing a technique for using entanglement for superluminal computation, which they claim they can carry out so long as no time travel paradoxes are caused: http://www.technologyreview.com/blog/arxiv/24903/ Here's their paper: http://arxiv.org/abs/1003.1238 Neat stuff!

Hello, I have heard the following from several places: The amount of information that can be stored within a sphere is equal to the amount of information that can be stored on its surface. This seems like a contradiction or, a self-defeating statement. It seems to instead say that a sphere can hold an infinite amount of information. For example: Since the amount of information you can put within the sphere is equal to the amount you can put on its surface… just put the information on its surface… then, with the interior of the sphere empty; put a slightly smaller sphere within and put more information on its surface then repeat this process until the spa…

Hi In an other thread, it was told that the electric field is in phase with the magnetic field in EM waves (photon). My question is: Is it possible (theoreticaly or in practice) to shift the magnetic field 90 degree of the electric field ? If yes what would be the result ? Would it produce a rotation of the photon ? Thanks in advance for your answers.

hi, I was wondering, shouldn't the outcome(s) of the double-slit experiment solve the observer effect / measurement problem ?

im relatively new to the whole quantum mechanics and quantum physics and everything, i was wondering if anyone had any ideas for books i can read or websites i can look at to help with my basic knowledge of this whole broad subject. im trying to teach myself the basics, and i apologize if i put this in the wrong forum

Hi, Even though it is called 'vacuum energy'... do we know or do we have some theory on... whether the activities of virtual particle pairs is the same whether in the relative vacuum of space or... with in ther Earth's atmosphere (where tests confirmed it) or... say inside a rock? Rusty

hi, Watch a short movie on quantum consciousness and was wondering how time at the atomic level, considered as not flow but continuous present moments of the now can be considered, via this, as moving backwards ?

hi, I was wondering, in the view our universe starting from the collision of 2 membranes, whereby the resultant energy and so forth of the collision caused the creation of what we see. And getting into how the collision could happen again (whatever time that may be in the future), how could the future collision of 2 membranes effect our present existing universe, because wouldn't the membranes simply pass through vastness of the vacuum? (excluding their possible effects on gravity etc)

I recently read some books about General Relativity, and how the "3-Brane" of standard spacetime is curved through the higher dimensional "hyperspace" of "The Bulk" (to use some String Theorist terms, as I've been told them). One of the books suggested that standard spacetime, which is like a thin sort of "shell" curving through hyperspace, could conceivably have some sort of "hyperspace thickness" -- and, that this thickness could account for things like the Pauli Exclusion Principal. For example, electrons might be "half as hyper-thick" as spacetime, so that you could "stack" two of them "over" each other, in the same stretch of space. Conversely, photons might be ve…

Hello all Recently I finished Brian Greene's book "The Fabric of the Cosmos". One statement stood out that said that if one could plot the motion and position of every quantum particle in the universe (impossible I know, because of the Heisenberg Uncertainty Principle, but mechanics aside) one could predict the future with 100% accuracy, or words to that effect. Does this mean that random chance and freedom of choice are illusions because that whatever happens happens because it must happen? Thanks in advance.

if rest mass of photon is zero!! when photon collides with a surface it will lose some energy satisfied by E2-E1 of metal. but at this time during collision photon comes to momentary rest(by some micro seconds)!!!!! does this mean at this time its mass is zero?? if so when it continues its motion where does it regain energy:rolleyes:

First of all.. I posted this thread under quantum mechanics because I think it has something to do with Max Planck,s equation. Anyway.. my text book says that the energy of light depends on it's frequency. Now this has me quite puzzled. In a mechanical wave, such as the wave one could make in a piece of string tied at one end to a fixed object, the energy arriving at the fixed end would be dependent on the amplitude of the wave of the string right? So why is this not true for electromagnetic waves? (I know there are many differences between electromagnetic waves and mechanical waves.. but I just can't figure out what makes the energy of one depend on the frequency a…

I was reading "QED" by Richard Feyman. I understand the method they used to calculate the possibility of partial reflection. But there is one thing that I just can't stop myself from thinking about it, (in the book, they say that the phenomenon of partial reflection can easily be explained by the wave theory of light. (the wave theory collapsed after the developed of instrument that can detect a single photon was invented.) My question was how was the partial reflection easily explained by the wave theory of light? (All that the book had mention was that wave can combine or cancel out, thus explained the partial reflection phenomenon.) But, how did that explain?…

Is it possible, to intentionally engineer structures, to be "nano-sharp", by manipulating the electron orbitals, on the "leading edge" of that structure ?

In Classical physics, particles are pure points, which form World-lines through Spacetime. Conversely, Quantum physics pictures particles as Wave Functions which are extended in space. Are Wave Functions extended in time, too ?
