超越模拟引力:异常动力学案例

Beyond Analog Gravity: The Case of Exceptional Dynamics

M. Novello, E. Goulart

摘要:

我们表明,它是可能超越简单的重力模拟模型的运动学方面。我们给出了描述自相互作用场$ ϕ$动力学的拉格朗日量的形式,它是$ ϕ$和它的有效度规$ \hat{g}^{μν}.$之间的相互作用。换句话说,场的非线性运动方程可以解释为引力通过它自己的有效度规对$ ϕ$的影响,在我们的方案中,它成为$ ϕ. $动力学的积极伙伴

英文摘要:

We show that it is possible to go beyond the simple kinematical aspects of the analog models of gravity. We exhibit the form of the Lagrangian that describes the dynamics of a self-interacting field $ ϕ$ as an interaction between $ ϕ$ and its associated effective metric $ \hat{g}^{μν}.$ In other words the non-linear equation of motion of the field may be interpreted as the gravitational influence on $ ϕ$ by its own effective metric which, in our scheme becomes an active partner of the dynamics of $ ϕ. $
