Main Question or Discussion Point

(Sorry for my poor English.)
How much of theory should one know in order to understand Gross-Pitaevskii equation, Fermi curves, metric tensor and so on? Is it necessary to took classes at the university or is it possible to learn those subjects just by self studying?

With enough practice and persistence anything can be learnt by self-study. But for what you mentioned you need to learn a lot - on the mathematical side significant amounts of linear algebra, real analysis, complex analysis, differential geometry, functional analysis, and a corresponding amount of theoretical physics. You may wish to look at the sections in Chapter C4: How to learn theoretical physics of my theoretical physics FAQ to get more advice on how to self-study successfully.
