在哈伯德模型的动态平均场理论 (DMFT) 的背景下,我们研究了有限温度下密度驱动莫特转变附近的压缩性行为。我们使用单频带和双频带 Hubbard 模型中的 DMFT 和量子蒙特卡罗模拟来证明这种分歧。我们根据朗道理论框架的考虑补充了这一结果,并讨论了我们的结果与铈的 α-γ 终点的相关性。
In the context of the dynamical mean-field theory (DMFT) of the Hubbard model, we study the behavior of the compressibility near the density driven Mott transition at finite temperatures. We demonstrate this divergence using DMFT and quantum Monte Carlo simulations in the one-band and the two-band Hubbard model. We supplement this result with considerations based on the Landau theory framework, and discuss the relevance of our results to the alpha-gamma end point in cerium.
