Fate of pseudo mobility-edge and multiple states in non-Hermitian Wannier-Stark lattice
Yu-Jun Zhao, Han-Ze Li, Xuyang Huang +2
The interaction between non-reciprocity and disorder-free localization has emerged as a fascinating open question. Here, we explore the effects of pseudo mobility edges (MEs) along…
Quantum engineering for compactly localized states in disordered Lieb lattices
Carlo Danieli, Jie Liu, Rudolf A. Römer
Blending ordering within an uncorrelated disorder potential in families of 3D Lieb lattices preserves the macroscopic degeneracy of compact localized states and yields unconvention…
Unconventional delocalization in a family of 3D Lieb lattices
Jie Liu, Carlo Danieli, Jianxin Zhong +1
Uncorrelated disorder in generalized 3D Lieb models gives rise to the existence of bounded mobility edges, destroys the macroscopic degeneracy of the flat bands and breaks their co…
Localization properties in Lieb lattices and their extensions
Jie Liu, Xiaoyu Mao, Jianxin Zhong +1
We study the localization properties of generalized, two- and three-dimensional Lieb lattices, and , and , at energies correspo…
Localization, phases and transitions in the three-dimensional extended Lieb lattices
Jie Liu, Xiaoyu Mao, Jianxin Zhong +1
We study the localization properties and the Anderson transition in the 3D Lieb lattice and its extensions in the presence of disorder. We com…
Disorder effects in the two-dimensional Lieb lattice and its extensions
Xiaoyu Mao, Jie Liu, Jianxin Zhong +1
We study the localization properties of the two-dimensional Lieb lattice and its extensions in the presence of disorder using transfer matrix method and finite-size scaling. We fin…
