In this talk, historically I will review the main aspects of new degrees of freedom appear at high temperature field theory calculations. I will try to illustrate main steps towards obtaining this quasiparticles and also give power counting rules needed for identifying which diagrams in Thermal Field Theory gain corrections due to this quasiparticles.

In heavy ion colliders huge magnetic fields arise after collisions due to motion of charged particles before collision. This produced giant magnetic field which is larger than the so called Schwinger limit of magnetic field is relevant for creation of particle-antiparticles pairs. Thus magnetic field should not be neglected in Heavy ion calculations. I try to find a solution to this questions that is there any similar quasi particles in the case of nonvanishing external magnetic field? What is the physical features of this new degrees of freedom?
