What happens when supercooling is terminated by curvature flipping of the effective potential?
收藏 引用
Journal of High Energy physics 2025年 第5期2025卷 1-35页
作者: Dutka, Tomasz P. Jung, Tae Hyun Shin, Chang Sub School of Physics Korea Institute for Advanced Study Seoul Republic of Korea Particle Theory and Cosmology Group Center for Theoretical Physics of the Universe Institute for Basic Science (IBS) Daejeon Korea Department of Physics and Institute of Quantum Systems Chungnam National University Daejeon Korea
We explore the nature of a certain type of supercooled phase transition, where the supercooling is guaranteed to end due to the curvature of the finite-temperature effective potential at the origin experiencing a sign...

Department of Physics Northeastern University BostonMA02115 United States Computational Science Initiative Brookhaven National Laboratory UptonNY11973 United States Center for Cosmology and Particle Physics Department of Physics New York University New YorkNY10003 United States
We demonstrate that wormholes must be entangled regardless of asymptotic boundary conditions. Assuming black hole complementarity, we argue that traversable wormholes instantiate entanglement-assisted quantum channels... 详细信息
