1+1维引力的新变量

New variables for 1+1 dimensional gravity

Rodolfo Gambini, Jorge Pullin, Saeed Rastgoo

摘要:

我们表明,规范制定的1+1-维模型的重力耦合到物质的通用行动承认的Ashtekar-type变量的描述。这包括CGHS模型和3+1引力球对称约化的特殊情况。这打开了讨论模型的黑洞蒸发使用循环表示技术和验证的范式出现的可能消除的黑洞奇异性和信息丢失的问题的可能性。

英文摘要:

We show that the canonical formulation of a generic action for 1+1-dimensional models of gravity coupled to matter admits a description in terms of Ashtekar-type variables. This includes the CGHS model and spherically symmetric reductions of 3+1 gravity as particular cases. This opens the possibility of discussing models of black hole evaporation using loop representation techniques and verifying which paradigm emerges for the possible elimination of the black hole singularity and the issue of information loss.
