I am having trouble understanding how to tell if a matrix is a tensor, a pseudo tensor or neither or the above.
Given this matrix
\begin{vmatrix}2x^-2y^2 & 4xy\\ 4xy & -2x^2+2y^2\end{vmatrix}
I thought of trying just inverting the components and checking the sign, but I don't think...
I need to take the 3-Dimensional Fourier transform of a point charge potential. I have an integral of this form, but I am unsure as to how to approach this integral.
\int e^{-i\vec{x}\vec{k}} \frac{q}{|\vec{x}-\vec{x'}|}d^3x
A push in the right direction would be appreciated.
I am a new graduate student, and I was hoping someone might recommend some journals to start reading. I have interests in solid state and quantum computation, but I am also somewhat undecided and would like a breadth of information to help me choose a path.
I am working on a homework assignment for my particle physics class, and it requires I understand what forces conserve what quantum numbers. As I understand it:
Strong
Conserves Isospin, I3 projection, s, c, b, t, Baryon number, lepton flavor
E&M
Conserves I3 projection, s, c, b...
I am a senior at University of Buffalo and am getting ready to start applying for graduate school. I was hoping that I could get some advice on where I should be looking, because I am having difficulty in finding a good list of schools with information on there areas of research. My interests...
I am now a senior and SUNY buffalo and a physics major, and my question is this. What are my chances of getting into a school such as Chicago or Colombia, maybe NYU or one of the UC schools. My scores are as follows

Here is where I'm stuck. Imagine an actual He atom with 2 electrons. What is the difference in there arrangement if they are in the singlet vs. triplet state so as to get different total spins.
Thanks for the quick reply, but I already understood that much. Where I'm lost is the physical significance of the triplet vs. singlet state in itself, not in regards to the spatial wave function. Basically what are the physical effects of being in one versus the other, but not due to the...
Mathematically I understand the difference between the singlet state |^v>-|v^> and the triplet state |^v>+|v^> but I can't figure out the physical difference. How are we arranging the electrons to get the 2 different total angular momentums (1 for triplet 0 for singlet)?
A diagram might help...
The problem that you are having comes from the diagram you are using. When you see something like this you should redraw it in an easier way to see it. Start with the battery, and connect it to the first resister. Then notice that the connection splits in three, so this means you can redraw...
For your first question, the easiest solution is to break all the forces up into there x and y components and then solve them this way
for example, the force that Harry exerts could be broken into
F_{x}= -400N sin(15)
F_{y}= -400N cos(15)
Once you do this for all the forces you can add...
You need to break it into two parts.
Force on the rocket from the earth
Force on the rocket from the moon
When these two forces are equal, then the net force acting on the rocket will be zero
To solve this you can write each of the first two parts in terms of the equation you gave, using...
Someone correct me if i am wrong, but i suspect the issue is that the medium in which the sound is traveling is also moving. In other words, even though it is the blood that is the source, it is also the medium that the sound is moving in. The result would be that you would have to treat the...
