Results II–Correlated Electrons Under Magnetic Field

After the discussion of high-Tc cuprate, we now turn our attention to another physical scenario of interest–the electrical mechanism under an external magnetic field. Physics of magnetism always plays an important role not only because there is a huge potential of industrial usage whether already exploited or not, but also nowadays we are welcome by a new era of physics of topological orders, which was first discovered experimentally within the materials involving magnetic field, the quantum Hall effect. Because of the fact that electrons possess a polarization of spins, they can be viewed as micro magnets and therefore their behavior under the thermal dynamics limit is exceptionally interesting. In this chapter we seek to provide another way of probing the micro magnetism from our numerical approaches, aiming at drawing more attention to this fruitful topic.
