Models based on the Color Glass Condensate (CGC) framework have been successful in explaining many experimental data from RHIC and LHC. However, applicability of these models are limited to a high transverse momentum region or one relies on the assumption of hadron-parton duality to compute multiplicity of the produced hadrons, because there are always non-perturbative effects in the...

Using the parton transport model BAMPS, the thermal equilibrium process for the dense gluon plasma produced in the early stages of ultra-relativistic heavy ion collisions is studyed, under the Color Glass Condensate inspired initial conditions. The bose enhancement effect's role in speeding up the growth of soft gluons is emphasized. Diffrent initial conditions is implemented into the model...

Entropy production in the early stage of relativistic heavy-ion collisions is studied based on the classical Yang-Mills (CYM) dynamics. CYM field is regarded as a coherent state, and then the von-Neumann entropy is calculated from the density matrix given by the coherent state assuming that the matrix is diagonal due to decoherence. We calculate the entropy in the non-expanding plasma from...

Anomaly-induced transport effects, like the chiral magnetic effect or the chiral separation effect, have recently attracted much attention. These effects represent the existence of dissipationless vector and axial currents along the magnetic field and are expected to occur in ultra-relativistic heavy-ion collisions. It has been pointed out that the coupling between the chiral magnetic effect...

63. Parametric instabilities in the earliest stage of heavy ion collisions

Instabilities play important roles in thermalization of heavy ion collisions since they may affect the emergence of chaoticity and field-particle conversions. In classical Yang-Mills fields, there are several known instabilities induced by color magnetic fields; Weibel and Nielsen-Olesen instabilities. We investigate instabilities of classical gluon fields under the homogeneous, but time...
