论文摘要
我们求解了一个多头矩阵模型，该模型近似于模糊球体上的实际四分之一标量场理论并获得其相图。我们将这种方法推广到具有修改的动力学术语的模型，并通过研究与去除UV/IR混合有关的模型来证明其使用。我们表明，对于模糊球体，通过高导数项对动作动作的动作部分进行了修改可以改变理论的相图，从而使三个点从原点进一步移动。
We solve a multitrace matrix model approximating the real quartic scalar field theory on the fuzzy sphere and obtain its phase diagram. We generalize this method to models with modified kinetic terms and demonstrate its use by investigating models related to the removal of the UV/IR mixing. We show that for the fuzzy sphere a modification of the kinetic part of the action by higher derivative term can change the phase diagram of the theory such that the triple point moves further from the origin.
