论文摘要
各种相变可能发生在早期的宇宙中，并且可能发生在重离子碰撞和超新星爆炸，原始恒星，冷紧凑型恒星以及在陆地条件下的凝结物中。最普遍地，可以在一阶和二阶相变的密度和温度的动力学借助非理想的流体动力学方程来描述。在给定的工作中，发现了一些新颖的解决方案，描述了在相变过程中形成的准碘结构的演变。尽管这种考虑是非常笼统的，但考虑到密集的baryon物质中的夸克 - 二龙和核液体 - 液体 - 液体一阶相变向均匀的k_0 = 0状态和pion冷凝物二阶相变向非均匀K_0 \ neq 0状态。
Various phase transitions could have taken place in the early Universe, and may occur in the course of heavy-ion collisions and supernova explosions, in proto-neutron stars, cold compact stars, and in the condensed matter at terrestrial conditions. Most generally, the dynamics of the density and temperature at first- and second-order phase transitions can be described with the help of the equations of non-ideal hydrodynamics. In the given work some novel solutions are found describing the evolution of quasiperiodic structures that are formed in the course of the phase transitions. Although this consideration is very general, particular examples of quark-hadron and nuclear liquid-gas first-order phase transitions to the uniform k_0=0 state and pion condensate second-order phase transition to non-uniform k_0\neq 0 state in dense baryon matter are considered.
