暴胀、相变和宇宙学常数

Inflation, phase transitions and the cosmological constant

Orfeu Bertolami

摘要:

宇宙学上的相变被认为发生在早期宇宙,并将它们的性质印刻在可观测的宇宙上。有强有力的证据表明,通过导致二阶相变的标量场的动力学,暴胀塑造了宇宙,解释了观测到的宇宙最显著的特征。有人认为,通货膨胀也有显着的影响,真空能量。随后的二阶相变的考虑也进行了讨论。

英文摘要:

Cosmological phase transitions are thought to have taken place at the early Universe imprinting their properties on the observable Universe. There is strong evidence that, through the dynamics of a scalar field that lead a second order phase transition, inflation shaped the Universe accounting for the most conspicuous features of the observed Universe. It is argued that inflation has also striking implications for the vacuum energy. Considerations for subsequent second order phase transitions are also discussed.
