Regge-Teitelboim宇宙学的Hamilton-Jacobi方法

Hamilton-Jacobi approach for Regge-Teitelboim cosmology

Alejandro Aguilar-Salas, Alberto Molgado, Efrain Rojas

摘要:

本文发展了由Regge-Teitelboim模型描述的测地膜状宇宙的Hamilton-Jacobi形式。我们专注于描述的完整的一套哈密顿量,确保可积的模型,除了获得汉密尔顿主函数$S$。为了做到这一点,我们通过适当地定义一组辅助变量来避免模型的二阶导数性质,这些辅助变量产生一阶拉格朗日。作为一个线性的加速理论,该计划必然需要一个适当的重新定义的所谓的广义泊松方程,以实现正确的发展,在约化相空间。此外,这个哈密顿-雅可比框架也使我们能够探索量子行为下的半经典近似的模型。与Ostrogradski-Hamilton方法的约束系统的比较也提供了详细的。

英文摘要:

The Hamilton-Jacobi formalism for a geodetic brane-like universe described by the Regge-Teitelboim model is developed. We focus on the description of the complete set of Hamiltonians that ensure the integrability of the model in addition to obtaining the Hamilton principal function $S$. In order to do this, we avoid the second-order in derivative nature of the model by appropriately defining a set of auxiliary variables that yields a first-order Lagrangian. Being a linear in acceleration theory, this scheme unavoidably needs an adequate redefinition of the so-called Generalized Poisson Bracket in order to achieve the right evolution in the reduced phase space. Further this Hamilton-Jacobi framework also enables us to explore the quantum behaviour under a semi-classical approximation of the model. A comparison with the Ostrogradski-Hamilton method for constrained systems is also provided in detail.
