假真空衰变的隧穿哈密顿表示:III。应用于暴胀宇宙的成核
The tunneling hamiltonian representation of false vacuum decay: III. Application to nucleation of an inflationary universe
摘要:
隧穿哈密顿量已被证明是一个有用的方法,在许多体物理学处理粒子隧穿之间的不同状态表示为波函数。在这里,我们适用于一种推广的方式,我们形成适当的波泛函CDW如何提出成核的暴胀宇宙。这使我们能够作出一个推广的模型用于通货膨胀时,暴胀子被困在一个假真空,隧道后,使一级相变开始成核的暴胀宇宙,其中隧道状态之间的波函数的标量量子场被认为是。我们解释了如何用粒子-反粒子对作为成核发生的模型,并构造了一个满足平慢滚条件的势,即使对这个问题使用了修改的假真空构造。
英文摘要:
The tunneling hamiltonian has proven to be a useful method in many body physics to treat particle tunneling between different states represented as wave functions. Here we apply a generalization of a way we formed appropriate wave functionals in CDW to how to present nucleation of an inflationary universe . This allows us to make a generalization of the model used for inflation when the inflaton is trapped in a false vacuum and, after tunneling, makes a first order phase transition to initiate nucleation of an inflationary universe, in which tunneling between states which are wavefunctionals of a scalar quantum field are considered . We explain how we can have particle - anti particle pairs as a model for how nucleation occurs and construct a potential which satisfies the flat slow roll condition even while using a modified false vacuum construction to this problem
