Deformation quantization of cosmological models

Ruben Cordero, Hugo Garcia-Compean, Francisco J. Turrubiates

摘要:

变形量子化的Weyl-Wigner-Groenewold-Moyal形式主义被应用于小超空间中的宇宙学模型。量子化过程是在一个平坦的小超空间量子宇宙学明确执行。详细推导了de Sitter宇宙学模型,数值计算了Hartle-Hawking、Vilenkin和Linde波函数的Wigner函数。本文对(非)对易量子宇宙学中的Kantowski-Sachs模型和具有介子指数势的弦宇宙学中的Wigner函数进行了解析计算。最后,婴儿宇宙的解决方案描述在这种情况下,维格纳函数得到。

英文摘要:

The Weyl-Wigner-Groenewold-Moyal formalism of deformation quantization is applied to cosmological models in the minisuperspace. The quantization procedure is performed explicitly for quantum cosmology in a flat minisuperspace. The de Sitter cosmological model is worked out in detail and the computation of the Wigner functions for the Hartle-Hawking, Vilenkin and Linde wave functions are done numerically. The Wigner function is analytically calculated for the Kantowski-Sachs model in (non)commutative quantum cosmology and for string cosmology with dilaton exponential potential. Finally, baby universes solutions are described in this context and the Wigner function is obtained.
