量子图形中的域结构
Domain structures in quantum graphity
摘要:
量子图形学提供了一个有趣的概念,即空间出现在动力学晶格的空间自由度的低能态中。在这里,我们调查亚稳域结构,这是可能存在于低能量阶段的晶格演化。通过退火过程中,我们探讨了形成亚稳态缺陷的畴边界和畴结构上的玻色子的传播的影响。我们表明,这些结构应该有可观察到的背景独立的后果,包括散射,双重成像,和引力透镜样的效果。
英文摘要:
Quantum graphity offers the intriguing notion that space emerges in the low energy states of the spatial degrees of freedom of a dynamical lattice. Here we investigate metastable domain structures which are likely to exist in the low energy phase of lattice evolution. Through an annealing process we explore the formation of metastable defects at domain boundaries and the effects of domain structures on the propagation of bosons. We show that these structures should have observable background independent consequences including scattering, double imaging, and gravitational lensing-like effects.
