2+1维中的点粒子:朝向半经典圈引力公式

Point particles in 2+1 dimensions: toward a semiclassical loop gravity formulation

Jonathan Ziprick

摘要:

利用三角剖分方法确定了2+1维一阶引力场中的联络和标架场,研究了2+1维一阶引力场中的点粒子。哈密顿量被简化为一个边界项,从而得到总质量。三角测量是动态的,当粒子遇到边缘时发生非平凡的转变。该框架有助于在环路重力相空间方面的描述。

英文摘要:

We study point particles in 2+1 dimensional first order gravity using a triangulation to fix the connection and frame-field. The Hamiltonian is reduced to a boundary term which yields the total mass. The triangulation is dynamical with non-trivial transitions occurring when a particle meets an edge. This framework facilitates a description in terms of the loop gravity phase space.
