摘要

本文讨论了在费米子理论中寻找非齐次手性对称性破缺的一种新方法。我们想到的主要应用是QCD，但该方法也适用于其他理论，包括固态应用。它是基于对非均相的手性敏感性的扩展，并作为一种稳定性分析。我们的方法使我们能够确定何时均质溶液有产生空间调制冷凝物的倾向。作为原理证明，我们将该技术应用于彩虹阶梯QCD模型，发现其相图包含一个非均匀区域。2025年由美国物理学会出版

New tool to detect inhomogeneous chiral-symmetry breaking

In this paper, we discuss a novel method to search for inhomogeneous chiral symmetry breaking in theories with fermions. The prime application we have in mind is QCD, but the method is also applicable for other theories, including solid state applications. It is based on an extension of the chiral susceptibility to inhomogeneous phases, and it works as a stability analysis. Our method allows us to determine when homogeneous solutions have the tendency to create spatially modulated condensates. As proof of principle, we apply this technique to a rainbow-ladder QCD model and find that its phase diagram contains an inhomogeneous region.
