论文摘要
我介绍了(扩展)proca-nuevo,这是一种非线性自旋-1领域的非线性理论,享有非线性实现的约束。我将提供一个协方差方案,该方案允许一致,无鬼魂的宇宙学解决方案,描述在存在完美流体物质的情况下正确数量的动态变量。我终于将展示出具有较晚自我加速时期的显式热爆炸解决方案,在该时期,所有稳定性和崇高性条件都得到满足,而引力波则与一般相对性一样。
I introduce (Extended) Proca-Nuevo, a non-linear theory of a massive spin-1 field enjoying a non-linearly realized constraint. I will provide a covariantization scheme that allows for consistent, ghost-free cosmological solutions, describing the correct number of dynamical variables in the presence of perfect fluid matter. I will finally exhibit explicit hot Big Bang solutions featuring a late-time self-accelerating epoch, where all the stability and subluminality conditions are satisfied and where gravitational waves behave precisely as in General Relativity.
