摇动但不搅动--耦合到量子引力的Potts模型
Shaken, but not stirred - Potts model coupled to quantum gravity
摘要:
我们在因果动力学三角剖分的框架下研究了耦合到二维洛伦兹量子引力的三态Potts模型的物质和几何的临界行为。相反的一般参数的影响,无序建议,我们发现强有力的数值证据表明,临界指数的物质的几何量子涨落的影响下,没有改变,相比其值固定,定期晶格。这进一步支持了先前的发现,即基于因果动力学三角剖分的量子引力模型在许多方面比它们的欧几里得模型表现得更好。
英文摘要:
We investigate the critical behaviour of both matter and geometry of the three-state Potts model coupled to two-dimensional Lorentzian quantum gravity in the framework of causal dynamical triangulations. Contrary to what general arguments of the effects of disorder suggest, we find strong numerical evidence that the critical exponents of the matter are not changed under the influence of quantum fluctuations in the geometry, compared to their values on fixed, regular lattices. This lends further support to previous findings that quantum gravity models based on causal dynamical triangulations are in many ways better behaved than their Euclidean counterparts.
