论文摘要
在本期刊上发表的最近发表的论文中[物理学。 Rev. B 97，075135（2018）]，Menezes等。分析在电磁场存在下在Lieb晶格上定义的有效骨骼模型的拓扑行为。在这种情况下，作者声称发现了准粒子的非典型量子厅效应。但是，与繁殖者治疗有关的一些不一致之处会危害该系统的主要结果。
In a recent paper published in this Journal [Phys. Rev. B 97, 075135 (2018)], Menezes et al. analyze the topological behavior of a effective bosonic model defined on the Lieb lattice in presence of an electromagnetic field. In this context, the authors claim to have found an atypical quantum Hall effect for the quasiparticles. However, some inconsistencies related to the treatment of the propagator jeopardizes the main result in this system.
