论文摘要
我们为基于Martin-Siggia-Rose形式主义的单一保守电荷的非线性波动流体动力学提供了有效的野外理论。将这种形式主义应用于只有电荷和多极的保守性的流体,并且在损坏的时间反向对称性的情况下,我们预测无限的许多新的动态通用类别,包括一些任意较大的上部临界维度。使用经典马尔可夫连锁店的大规模模拟,我们发现数值证据表明,在一个空间维度中,具有损坏的时间反向对称性的四极杆稳定模型中流体动力学的分解。
We present an effective field theory for the nonlinear fluctuating hydrodynamics of a single conserved charge with or without time-reversal symmetry, based on the Martin-Siggia-Rose formalism. Applying this formalism to fluids with only charge and multipole conservation, and with broken time-reversal symmetry, we predict infinitely many new dynamical universality classes, including some with arbitrarily large upper critical dimensions. Using large scale simulations of classical Markov chains, we find numerical evidence for a breakdown of hydrodynamics in quadrupole-conserving models with broken time-reversal symmetry in one spatial dimension.
