How do i do ? i still have no idea of how to find it

Im still stuck atm

Homework Statement Im doing a MC simulation with the ising model 2D. How can i calculate the Binder cumulant g as a function of temperature. To calculate the Binder cumulant, i will perform a scaling analysis f (finite scale scaling). Homework Equations U_L = 1 – { M^(4)_L / [ 3.(M^(2)_L)^2 ]...

I solved it

Im still stuck, why do i get a different answer ?

Why is my solution wrong ?

Homework Statement I want to solve the motion equation ## m \frac {dv_z} {dt} = - μ \frac {∂B_z} {∂z} ## with small angle approximation Homework Equations ## B_z(z) = B_0 -bCos(\frac {zπ} {2L}) ## is the magnetic field in the z-direction The Attempt at a Solution Started by derive the...

Homework Statement An electromagnetic wave with the frequency f = 1.4 GHz is propagating in the z-direction from vacuum in a plasma with the magnetic field ## B_0 = 0.1T \hat z ##. The plasma density is ## 1.0*10^{17} ## ## \frac {particles} {m^3} ##. The wave is then separated into a R- and...

Homework Statement An electromagnetic wave with the frequency f = 1.4 GHz is propagating in the z-direction from vacuum in a plasma with the magnetic field B_0 = 0.1T z^. The plasma density is 1.0*10^17 particles/m^3. The wave is the separated into a R- and L-wave in the plasma. Homework...

Someone that knows what iam missing ?

No, I am still stuck atm. Cant get any reasonable graph. Is there someone that have done this type of simulation before ?

Homework Statement Lo,Im stuck on how to retrieve the specific heat capacity from an MC simulation, with the metropolis algorithm. I want my graph to look something like this: https://i.stack.imgur.com/NXeXs.png Homework Equations C_v = ((<E^2>-<E>^2)/T^2 The Attempt at a Solution My code is...

Yes i know. But i still don't see why S^2−D^2≠1 has to be the case. And why is the plasma frequency wrong ?

Ok A high frequency electromagnetic wave in a cold magnetized plasma with the density n_0 is polarized with the electromagnetic field in the same direction as the magnetic field B_0 = B_0z^. Namely E^~ = E_0exp(i(kx-ωt))z^ 1) Determine the dispersion relation for the wave 2) Determine the...

Homework Statement Im stuck on a old exam in plasma physics. It is about how to determine dispersion relations for high frequency waves in cold plasma's. I'm not sure how they do in the solution manual. Homework Equations B = B_0z^ E = E_0exp(i(kx-wt))z^ The Attempt at a Solution The...
