But then why when I calculate the scattering matrix of my system I see resonances only for the quarter wavelength condition? In other words why can I only probe the parallel resonance of the RLC? Is it related to the definition of the scattering matrix which is the ratio between the input...

Hello everyone, I am studying transmission line resonators and in particular I was considering a particular case of resonator where I have an open circuited quarter wavelength transformer of high impedance terminating a regular 50 ##\Omega## line. If I look at the input impedance from the open...

Thank you! I think I will follow your approach, trying to keep myself trained doing small exercise (like the ones of the GRE) from time to time

Because I will be defending my master thesis in one month and starting my phd in 2 (January 2017). So I actually finished the "studying" part, meaning that I don't have any more class to attend.

I focused my studies most on atomic and solid state physics. And in the end I will work mainly on superconductivity.

Hello everyone! I am about to finish my master degree and to start my PhD and I am very excited about it! There is something, though, that worries me a bit: sometimes I feel I don't have very good and solid basis. May be due to forgetfulness with time or due to a bad study when I was younger and...

With that it would be actually preatty easy. But if I want to find the matrix form such $$H \begin{pmatrix} n_a \\ n_b \end{pmatrix} = E \begin{pmatrix} n_a \\ n_b \end{pmatrix}$$ what should I do?

Sorry I forgot to specify, J is the coupling coefficient between the two cavities

Hello everyone! For my quantum mechanics class I have to study the problem of two quantum oscillator coupled to each other and in particular to find the eigenstates and eigenergies for a subspace of the Fock space. I know that, in general, to solve this kind of problem I have to diagonalize the...

Hello everyone! I am a physics student, I just discovered this forum and I think it's pretty amazing!
