摘要:

在过去的十年里,在理解三维(2+1维)时空中与点粒子耦合的量子引力方面取得了重大进展。最值得注意的是,这个理论可以被有效地描述为一个动量空间上的自由粒子理论,这个动量空间具有反deSitter几何和$[x^μ,x^ν]=i \hbar \ell \varepsilon^{μν}_{\phantom{μν}ρ} x^ρ$型的非对易时空坐标。我们在这里表明,最近提出的相对局域性弯曲的动量空间框架是非常适合容纳这些结构的三维量子引力的特点。由此我们得到了三维量子引力的DSR变形庞加莱对称性的一个直观刻画,并发现相应的相对时空定域性是产生双引力透镜的类型.

英文摘要:

Over the last decade there were significant advances in the understanding of quantum gravity coupled to point particles in 3D (2+1-dimensional) spacetime. Most notably it is emerging that the theory can be effectively described as a theory of free particles on a momentum space with anti-deSitter geometry and with noncommutative spacetime coordinates of the type $[x^μ,x^ν]=i \hbar \ell \varepsilon^{μν}_{\phantom{μν}ρ} x^ρ$. We here show that the recently proposed relative-locality curved-momentum-space framework is ideally suited for accommodating these structures characteristic of 3D quantum gravity. Through this we obtain an intuitive characterization of the DSR-deformed Poincaré symmetries of 3D quantum gravity, and find that the associated relative spacetime locality is of the type producing dual-gravity lensing.
