The K/pi ratio from condensed Polyakov loops
O. Scavenius, A. Dumitru, J. T. Lenaghan
We perform a field-theoretical computation of hadron production in large systems at the QCD confinement phase transition associated with restoration of the Z(3) global symmetry. Th…
Explosive Decomposition in Ultrarelativistic Heavy Ion Collision
O. Scavenius, A. Dumitru, A. D. Jackson
Recent results from Au+Au collisions at BNL-RHIC energy hint at explosive hadron production at the QCD transition rather than soft hydrodynamic evolution. We speculate that this is…
First-Order Chiral Phase Transition in High-Energy Collisions: Can Nucleation Prevent Spinodal Decomposition?
O. Scavenius, A. Dumitru, E. S. Fraga +2
We discuss homogeneous nucleation in a first-order chiral phase transition within an effective field theory approach to low-energy QCD. Exact decay rates and bubble profiles are ob…
Nonlinear evolution of the momentum dependent condensates in strong interaction: the ``pseudoscalar laser''
Adrian Dumitru, Ove Scavenius
We discuss the relaxation of the scalar and pseudoscalar condensates after a rapid quench from an initial state with fluctuations. If we include not only the zero-mode but also hig…
First-order chiral phase transition may naturally lead to the ``quenched'' initial condition and strong soft-pion fields
O. Scavenius, A. Dumitru
We propose a novel mechanism for DCC formation in a first-order chiral phase transition. In this case the effective potential for the chiral order parameter has a local minimum at…
Chiral Fluid Dynamics and Collapse of Vacuum Bubbles
Igor N. Mishustin, Ove Scavenius
We study the expansion dynamics of a quark-antiquark plasma droplet from an initial state with restored chiral symmetry. The calculations are made within the linear model scale…
