Hi.
I am trying to perform a tensor product between two 2x2 matrices using Mathematica.
When i simply use the symbol for tensor product and put it between the two matrices, the program just reproduce the same expression when i execute it.
I tried to multiply the individual elements of...
Hi.
I am sorry, but i don't understand what you mean by writing the hamiltonian in the p basis.
(and i will remember to post such problems in the Homework Help section next time, sorry about that :-p )
Hi. I have this problem which i am stuck at:
Consider a one-dimensional Hamilton operator of the form
H = \frac{P^2}{2M} - |v\rangle V \langle v|
where the potential strength V is a postive constant and |v \rangle\langle v| is a normalised projector, \langle v|v \rangle = 1 ...
Hi.
Can pair production happen in vacuum?
I had this question for a test. And the answer is: no, it cannot because it would violate the conservation of momentum, since you can't have a momentum zero photon.
But i seem to recall that pair production happen in space (?). Due to...
Hi.
In general, how does one find the eigenvalues of an operator?
I have a problem which goes like this:
Consider a 1-D Hamilton operator of the form:
H = (P^2)/2M - |v> V <v| ,
where the potential strength V is a positive constant and |v><v| is a normalised projector, <v|v> =...
