项目摘要
We have succeeded in numerically solving the classical Yang-Mills equations with the realistic initial conditions called Glasma. Computing the Kolmogorov-Sinaii entropy, we have shown that entropy is created even in the classical field dynamics. It is found that small but finite initial fluctuations of the gauge field are indispensable for the entropy creation,We have also identified the coherent state as the corresponding quantum state for the classical fields, and obtained the time evolution of the coherent state through the classical Yang-Mills dynamics. We have calculated the entropy from the multiplicities of the particle derived from thus obtained choherent state, and found that entropy is created once small but finite fluctuations of the initial state is taken into account.We have shown that if the hydrodynamics should be the infrared dynamics around thermal equilibrium, the first-order relativistic hydrodynamics must be the one by Landau and Lifshitz.
我们已经成功地以称为Glasma的现实初始条件来求解经典的Yang-Mills方程。计算kolmogorov-sinaii熵,我们已经证明了熵是在经典的场动力学中也创建的。发现仪表场的较小但有限的初始波动对于熵创建是必不可少的,我们还确定了连贯的状态为经典磁场的相应量子状态,并通过经典的Yang-mills动力学获得了相干状态的时间演化。我们已经根据从这样获得的粒子得出的粒子的多样性计算出熵,并发现一旦考虑到初始状态的微小但有限的波动就可以创建熵。
