Thank you both very much!
Would it be right to say that an entangled state, links the probabilities of the spin (sometimes could be another property) of two particles?
I think part of the misconception is that sometimes the spin of a single particle in the above state is also sometimes referred...
Thank you very much,
I was able to find articles on entropy with that definition,
So the change in entropy is
ΔS=∫q/T dT
and entropy itself is defined as
S=kb*lnΩ
with Ω being the number of configurations
So if entropy is related to the number of possible configurations of a state so I can...
Dictionary definitions of it that I find define it that way but I can understand them being poor sources, could you link me a good source for what entropy really is then?
This is an observation I'm making that seems like it is wrong but I can't figure out why it would be.
Entanglement links two states together. For example the spin angular momentum of particles. An entangled state of two particles could be where you know if one particle is measured spin up the...
I’m confused about how you find the vector |s;s⟩ to use in the general equation
|θ,ϕ⟩=exp(−iϕS3) * exp(−iθS2) |s;s⟩
For spin Coherent states (From http://www.scholarpedia.org/article/Coherent_state_(Quantum_mechanics)#4._Spin_Coherent_States
Eq 12)
Or
how you find the vector |j,m=j⟩ to use...
Thank you, Those are what I'm looking at, I suppose I made the mistake in thinking the coherent state for the harmonic oscillator was the same because its equation is a similar format to the one I'm looking at.
The main difference is that the state I need to find is represented by |j,j> but I'm...
I've found online that the coherent state of the harmonic oscillator is
|\alpha \rangle = c \sum_{n=0}^\infty \frac{\alpha^n}{\sqrt{n!}} | n\rangle
where
|n\rangle = \frac{(a^\dagger)^n}{\sqrt{n!}} |0\rangle
and |0> is called the initial state.
I've some code where I need to have this...
