Double-layered vacuum bubbles and cosmological phase transitions
Dongdong Wei, Zong-Kuan Guo, Qiqi Fan
We investigate the evolution and formation of double-layered vacuum bubbles during cosmological phase transitions with multiple vacua. We employ lattice simulations to show that fl…

Cosmological first-order phase transitions without bubbles
Dongdong Wei, Haibin Chen, Qiqi Fan +1
In the traditional view a cosmic first-order phase transition cannot occur without nucleating handful of bubbles in the entire Hubble volume. The presence of domain walls during th…
