Is false vacuum theory real
WebIt is possible for a classical field theory to have two homogeneous stable equilibrium states with different energy densities. In the quantum version of the theory, the state of higher energy density becomes unstable through barrier penetration; it is a false vacuum. This is the first of two papers developing the qualitative and quantitative semiclassical theory of …

WebOne caveat is that if the Universe is a false vacuum that locally decays into a Minkowski or a Big Crunch -bound anti-de Sitter space in less than 20 billion years, then infinite Boltzmann nucleation is avoided. WebThe false vacuum theory has been used to explain a variety of phenomena in the universe, including the early universe inflationary period, the formation of galaxies, and the accelerated expansion of the universe. ... Some scientists believe that false vacuum decay is a real phenomenon that could lead to the end of the universe as we know it ...

We design and implement a quantum laboratory to experimentally observe and study dynamical … WebNov 13, 2011 · Edit: On the other hand, a false vacuum is given by a tachyonic state with negative mass square, not by an unstable particle, whose complex mass has a positive real part. Thus it corresponds to a unitary but unphysical representation of the Poincare group.

In this talk, we discuss a method of approximating the time scale on which a false vacuum is stable to quantum fluctuations in a quantum field theory (QFT). Fig: The string theory landscape black and decker rice and vegetable steamerIn quantum field theory, a false vacuum is a hypothetical vacuum that is relatively stable, but not in the most stable state possible. This condition is known as metastable. It may last for a very long time in that state, but could eventually decay to the more stable state, an event known as false vacuum decay. … See more A vacuum is defined as a space with as little energy in it as possible.
