本研究受零无穷远渐近平直时空问题启发,以二维无质量标量场为例,探讨零超平面上正则表述的相关微妙问题,涉及对称性、零模处理等内容,为相关量子化研究提供参考。

摘要:

受零无穷远渐近平直时空相关问题的启发,我们以二维无质量标量场这一最简单的例子,讨论了在单个或两个相交零超平面上建立正则表述时出现的若干微妙问题,重点关注无穷维整体对称性与共形对称性及其正则生成元、自由数据、零模的自洽处理、匹配条件,以及无质量场与有质量场量子化的相关影响。

英文摘要:

Motivated by issues in the context of asymptotically flat spacetimes at null infinity, we discuss in the simplest example of a massless scalar field in two dimensions several subtleties that arise when setting up the canonical formulation on a single or on two intersecting null hyperplanes with a special emphasis on the infinite-dimensional global and conformal symmetries and their canonical generators, the free data, a consistent treatment of zero modes, matching conditions, and implications for quantization of massless versus massive fields.
