论文摘要
我们提出了一个称为phaseTracer的C ++软件包，用于绘制宇宙学阶段，并在其之间进行潜在的过渡，以用于具有任何数量的标量字段的标准模型扩展。随着温度的变化，phasetracer会追踪有效电位的最小值，然后计算临界温度，在该温度变化时，最小值是变性的。假量的构建具有模块化，灵活性和实用性。它是快速稳定的，可以收到其他软件包（例如Flexiblesy）提供的潜力。相位量表可以是有用的分析宇宙学相变，这些宇宙期在宇宙的早期演变中起着重要作用。如果它们是一阶，则可以产生可检测的引力波和/或触发电动性男性生成，从而产生观察到的物质抗物不对称性。该代码可以从https://github.com/phapentracer/phassetracer获得。
We present a C++ software package called PhaseTracer for mapping out cosmological phases, and potential transitions between them, for Standard Model extensions with any number of scalar fields. PhaseTracer traces the minima of effective potential as the temperature changes, and then calculates the critical temperatures, at which the minima are degenerate. PhaseTracer is constructed with modularity, flexibility and practicality in mind. It is fast and stable, and can receive potentials provided by other packages such as FlexibleSUSY. PhaseTracer can be useful analysing cosmological phase transitions which played an important role in the very early evolution of the Universe. If they were first order they could generate detectable gravitational waves and/or trigger electroweak baryogenesis to generate the observed matter anti-matter asymmetry of the Universe. The code can be obtained from https://github.com/PhaseTracer/PhaseTracer.
