vacuümdecay
Vacuümdecay, also written as vacuum decay, is the hypothetical transition of a metastable vacuum state to a lower-energy true vacuum in quantum field theory. In such scenarios, a field may reside in a local minimum of its potential—a false vacuum—while a deeper minimum exists at higher field values. If a false vacuum is metastable, quantum tunneling or thermal fluctuations can nucleate bubbles of true vacuum, which can grow and convert neighbouring regions of space to the new vacuum state.
The decay process is described using semiclassical methods that rely on instanton solutions, often referred to
In the Standard Model of particle physics, discussions of vacuum stability focus on the Higgs potential. With
Vacuümdecay remains a theoretical construct with profound implications for cosmology and fundamental physics, illustrating how the
