9988720Boyanovsky Recent results from CERN seem to indicate that a new form of matter predicted by the strong interactions, i.e, the quark gluon plasma can be produced in ultrarelativistic heavy ion collisions. Current and forthcoming experiments at the Relativistic Heavy Ion Collider at Brookhaven and the Large Hadron Collider at CERN with higher energies and luminosity will access this new state of matter which existed a few microseconds after the Big Bang. This proposal describes the continuation of a program to study non-equilibrium aspects of the phase transitions that lead to the formation and evolution of this novel plasma. The goal of this program is to find experimental signatures of these transitions associated with strongly out of equilibrium phenomena by adapting and implementing novel techniques of non-equilibrium quantum statistical physics to study phenomena on time scales of 10^-22 seconds and spatial scales of 10^-14 meters. The program has experimental relevance for the search of the quark-gluon plasma and phase transitions at RHIC and LHC with potential for interdisciplinary impact in cosmologyand condensed matter physics.

最近来自CERN的研究结果似乎表明，在超相对论重离子碰撞中可以产生一种由强相互作用预言的新的物质形式，即夸克胶子等离子体。目前和即将在布鲁克海文的相对论重离子对撞机和欧洲核子研究中心的大型强子对撞机上进行的具有更高能量和亮度的实验将访问大爆炸后几微秒存在的这种新物质状态。该提案描述了一个程序的继续，以研究非平衡方面的相变，导致这种新型等离子体的形成和演变。该计划的目标是通过调整和实施非平衡量子统计物理学的新技术来研究10^-22秒时间尺度和10^-14米空间尺度上的现象，从而找到与强烈失衡现象相关的这些跃迁的实验特征。该计划与RHIC和LHC的夸克-胶子等离子体和相变的研究具有实验相关性，具有在宇宙学和凝聚态物理学中产生跨学科影响的潜力。
