常见晶格上源于相消干涉的子晶格极化

Sublattice polarization from destructive interference on common lattices

Yu-Ping Lin

AI总结:

该研究揭示常见晶格上普遍存在子晶格极化态,提出基于点群对称性的相消干涉机制,推导其对称性保护鲁棒性,可推广至多子晶格极化情形,并分析了对相互作用驱动相的重要影响。

摘要:

我们证明子晶格极化态(SLPSs)在常见晶格上普遍存在。首先建立了SLPSs的相消干涉(DI)机制,并通过点群对称性解释对其进行了系统化。随后展示了常见一维、二维和三维晶格上的实例。我们还推导了SLPSs针对次近邻跃迁的对称性保护鲁棒性。此外,DI机制可推广至多子晶格极化(multi-SLP)情形。通过Hartree-Fock分析研究了其对相互作用驱动相的重要影响。

英文摘要:

We show that sublattice-polarized states (SLPSs) appear ubiquitously on the common lattices. We first establish the destructive-interference (DI) scenario for the SLPSs, which is systematized by a point-group-symmetry interpretation. The examples on common one-, two-, and three-dimensional lattices are then demonstrated. We also deduce the symmetry-protected robustness of SLPSs against further-neighbor hoppings. Moreover, the DI scenario can be generalized to the multi-SLP. The important effects on interaction-driven phases are studied by Hartree-Fock analysis.
