标题： Mirror symmetry breaking with limited enantioselective autocatalysis and temperature gradients: a stability survey

摘要： 我们分析在温度梯度和热材料与冷材料的内部流动/循环下的有限对映选择性（LES）自催化作用。 微可逆性禁止在仅有温度梯度的情况下LES出现打破镜像对称性。 然而，当自催化作用和有限对映选择性催化分别局限于低温区和高温区时，这种对称性可以被打破。 该方案最近被提出作为深海热液喷口中手性自发出现的合理模型。 在化学参数空间中绘制出消旋状态不稳定并分叉为手性解的区域。 显示英文摘要

摘要： We analyze limited enantioselective (LES) autocatalysis in a temperature gradient and with internal flow/recycling of hot and cold material. Microreversibility forbids broken mirror symmetry for LES in the presence of a temperature gradient alone. This symmetry can be broken however when the auto-catalysis and limited enantioselective catalysis are each localized within the regions of low and high temperature, respectively. This scheme has been recently proposed as a plausible model for spontaneous emergence of chirality in abyssal hydrothermal vents. Regions in chemical parameter space are mapped out in which the racemic state is unstable and bifurcates to chiral solutions.
