Thanks, but my professor gave us a list with a lot of problems to solve, and I found that some of them are from Sakurai's Advanced QM book. Would be good if I had somewhere to check if I did these problems in the right way... But thanks anyway. Leticia

Does someone know a site with Sakurai (Advanced QM) solved problems? Thanks in advance, Leticia

Thanks. I'll look for this book online, 'cos I don't have it... :(

Homework Statement I need to solve the Klein-Gordon-Schrodinger and the Dirac equation for the Coulombian potential.Homework Equations KGS: [(\partial^{\mu}\partial_{\mu} + m^2c^2/h^2)\Psi=0 I don't know how I can add the potential term... Dirac: [\gamma^{\mu}(ih\partial_{\mu} - (e/c)...

Thanks, I'll think about this...

Do you mean the motion equations?

Yes, exactly this Lagrangian, where \Psi is a scalar field.

1. Special Relativity 2. Homework Statement Consider this Lagrangian: L=(1/2) (\partial_{\mu} \Psi)(\partial^{mu} \Psi) + \exp(-(a\times \Psi)^2) Have this field a mass term?Homework Equations The Attempt at a Solution
