$f\left(T,B\right) $宇宙学的微超空间量子化

Minisuperspace Quantization of $f\left(T,B\right) $ Cosmology

Andronikos Paliathanasis

摘要:

本文讨论了广义四阶远程平行宇宙理论$f\left( T,B\right) $在小超空间中的量子化。具体地说,我们关注的情况下,该理论是线性的扭转标量,在考虑到我们能够写的宇宙场方程的使用标量场不同的标量张量理论,但与相同的动力学约束的标量张量理论。我们首次用小超空间描述写出惠勒-德维特方程。利用相似变换理论,我们可以找到Wheeler-DeWitt方程的精确解,也可以研究量子力学的deBroglie-Bohm表象中的经典极限和半经典极限。

英文摘要:

We discuss the quantization in the minisuperspace for the generalized fourth-order teleparallel cosmological theory known as $f\left( T,B\right) $. Specifically we focus on the case where the theory is linear on the torsion scalar, in that consideration we are able to write the cosmological field equations with the use of a scalar field different from the scalar tensor theories, but with the same dynamical constraints as that of scalar tensor theories. We use the minisuperspace description to write for the first time the Wheeler-DeWitt equation. With the use of the theory of similarity transformations we are able to find exact solutions for the Wheeler-DeWitt equations as also to investigate the classical and semiclassical limit in the de Broglie -Bohm representation of quantum mechanics.
