How to describe solid state

[Neitrino]

Hi,

Is there in a Solid State (condensed matter) physics any function that describes the condition\ property of the system (material)? I mean like in a field theory when giving a Lagrangian of a fields it is the starting point to describe that system...


Thanks

I'm not sure I understand what you're asking here. Condensed matter is no different than other areas of physics. We DO start with the Hamiltonian of the system that we want to study. And field theoretic method is typically used - that's why we have all of these gauge bosons floating around in many of the condensed matter systems.
