用f(T)引力中的标量场重建的某些问题

Some aspects of reconstruction using a scalar field in f (T ) Gravity

Soumya Chakrabarti, Jackson Levi Said, Gabriel Farrugia

摘要:

广义相对论将引力描述为大质量物体在时空上表现出的几何性质,而远平行引力则通过对引力的扭转视角,在方程的层面上获得了同样的结果。类似于f(R)理论,遥平行引力也可以推广到f(T),由此产生的场方程本质上不同于f(R)引力,因为它们是二阶的,而在前一种情况下,它们是四阶的。在这种情况下,一个最小耦合标量场的研究在f(T)重力的背景下,几种形式的标量场的潜力。一些新的f(T)的解决方案被发现这些潜力,其各自的状态参数也被检查。

英文摘要:

General relativity characterizes gravity as a geometric property exhibited on spacetime by massive objects while teleparallel gravity achieves the same results, at the level of equations, by taking a torsional perspective of gravity. Similar to f (R) theory, teleparallel gravity can also be generalized to f (T ), with the resulting field equations being inherently distinct from f (R) gravity in that they are second order, while in the former case they turn out to be fourth order. In the present case, a minimally coupled scalar field is investigated in the f (T ) gravity context for several forms of the scalar field potential. A number of new f (T ) solutions are found for these potentials, with their respective state parameters also being examined.
