The real problem is
I get the expectation value of the commutator to zero, even for operator | 45>. This can not be correct. I can not solve this problem, can you help me?
I'm trying to extract the expected value of a |+45> polarized photon in the HV- base. I do it in two ways, one is correct and the other I get wrong answer. What am I doing wrong in the first method that is wrong?
method 1
method 2
thanks in advance
"Since the photon statistics follow a Poisson distribution you can achieve sources with a well defined probability ratio for the emission of one versus two or more photons"
I do not really understand how the connection between reducing intensity and Poisson distribution. If we have 10 ^ 15...
Hi!
We will make a lab analogous to the stern gerlach experiments but with polarized light. How can we get only one single photon in experiment with a coherent light source? I'm going to make a lab where we need to get in only one single photo at a time. I have read that you can use some...
A particle of mass m comes with the speed 0.6c and collides with another particle of mass m which is at rest. In the collision melts the particles together and form a particle. What is the mass and velocity of the particle is formed?
solution:
The momentum and the total energy is conserved...
The solution for a is 10 years. How I came up with this, You can take a look to the picture below.
"How far away was Tom/Astrid when he/she turned around, and which year was on Earth then (as seen from earth)?"
the answer is as seen from earth, she is 3 lightyears away from the Earth and and...
Hi!
I have difficulty with the English language but will try my best. I have recently begun to study the theory of special relativity. , I understand what the relativity of time is, relativity of length and Lorentz transformations. But I still have difficulty with solving data and do not know...
