论文摘要
我们在接近有序阶段研究了马尔萨斯碳酸氢糖理论的特性。由于出生/死亡过程，这种马尔萨斯模型的特征，密度波动被部分抑制。我们使用扰动重新归一化组研究了该模型。在一个循环中，我们发现重新归一化的组流动在不稳定区域中驱动系统，这表明诱导的一阶相变。
We study the properties of the Malthusian Toner-Tu theory in its near ordering phase. Because of the birth/death process, characteristic of this Malthusian model, density fluctuations are partially suppressed. We study this model using the perturbative renormalization group. At one loop we find that the renormalization group flow drives the system in an unstable region, suggesting a fluctuation-induced first-order phase transition.
