Emergence of Coherent Long Wavelength Oscillations After a Quench: Application to QCD

چکیده
To model the dynamics of the chiral order parameter in a far from equilibrium phase transition, we consider quenching in the O(4) linear sigma model. We argue, and present numerical evidence, that in the period immediately following the quench long wavelength modes of the pion field are amplified. This results in large regions of coherent pion oscillations, and could lead to dramatic phenomenological consequences in heavy ion collisions.

Emergence of long wavelength pion oscillations following a rapid QCD phase transition
To model the dynamics of the chiral order parameter in a far from equilibrium QCD phase transition, we consider quenching in the O(4) linear sigma model. We summarize arguments and numerical evidence which show that in the period immediately following the quench arbitrarily long wavelength modes of the pion field are amplified. This results in large regions of coherent pion oscillations, and co...
متن کاملThe Chiral Phase Transition in Qcd: Critical Phenomena and Long Wavelength Pion Oscillations
In QCD with two flavours of massless quarks, the chiral phase transition is plausibly in the same universality class as the classical four component Heisenberg magnet. Therefore, renormalization group techniques developed in the study of phase transitions can be applied to calculate the critical exponents which characterize the scaling behaviour of universal quantities near the critical point. ...
متن کاملNonequilibrium Quantum Dynamics of Second Order Phase Transitions
We use the so-called Liouville-von Neumann (LvN) approach to study the nonequilibrium quantum dynamics of time-dependent second order phase transitions. The LvN approach is a canonical method that unifies the functional Schrödinger equation for the quantum evolution of pure states and the LvN equation for the quantum description of mixed states of either equilibrium or nonequilibrium. As nonequ...
متن کاملDisorienting the Chiral Condensate at the Qcd Phase Transition
I sketch how long wavelength modes of the pion field can be amplified during the QCD phase transition. If nature had been kinder, and had made the pion mass significantly less than the critical temperature for the transition, then this phenomenon would have characterized the transition in thermal equilibrium. Instead, these long wavelength oscillations of the orientation of the chiral condensat...
متن کاملSupercurrent survival under a Rosen-Zener quench of hard-core bosons.
We study the survival of supercurrents in a system of impenetrable bosons on a lattice, subject to a quantum quench from its critical superfluid phase to an insulating phase. We show that the evolution of the current when the quench follows a Rosen-Zener profile is exactly solvable. This allows us to analyze a quench of arbitrary rate, from a sudden destruction of the superfluid to a slow openi...
