非平凡拓扑时空中的基态能量和拓扑质量

Ground state energy and topological mass in spacetimes with nontrivial topology

Paulo J. Porfírio, Herondy F. Santana Mota, Gabriel Queiroz Garcia

摘要:

本文研究了准周期明可夫斯基时空和“半爱因斯坦宇宙”(即无质量标量场在Dirichlet边界条件下传播的爱因斯坦宇宙)中无质量标量场的基态能量和拓扑质量的产生.进行分析,考虑在这两种情况下的有效电位的一个和两个回路的校正。我们的研究结果与文献中发现的结果进行了比较。

英文摘要:

In the present paper, we investigate the ground state energy of a massless scalar field and generation of topological mass by considering a quasi-periodically identified Minkowski spacetime and the `half-Einstein Universe', that is, an Einstein Universe where the massless scalar field propagates under Dirichlet boundary condition. The analysis is performed considering one and two-loop corrections to the effective potential in both cases. Our results are compared with previous results found in literature.
