Main Question or Discussion Point
I am no familiar with this area, and I want to know whether can we say that materials including atoms with d electrons are strongly correltated sysytem?
You do know that you're asking a question that is the topic of whole books.leoant said:I am no familiar with this area, and I want to know whether can we say that materials including atoms with d electrons are strongly correltated sysytem?
But that is a central research work in condensed matter. What model one can use it extremely important. One model that works in one situation may not work in another. It very much depends on the nature of the problem. If you have, for example, a Kondo system, then even perturbative approach may fail since for this system, one of the higher order interaction is LARGE.leoant said:Ohh, it's an exciting paper while makes me frustrated. One can interpret 'the complex system' intuitively, however, how can we describe it mathematically?
Using Hubbard mode or t-J mode? Or even chaos theory?
