Anomalous quantized nonlinear soliton pumping
Yu-Liang Tao, Jiong-Hao Wang, Yong Xu
It has recently been theoretically predicted and experimentally observed that a soliton resulting from nonlinearity can be pumped across an integer or fractional number of unit cel…
Topological Order and Non-Hermitian Skin Effect in Generalized Ideal Chern Bands
Jiong-Hao Wang, Christopher Ekman, Raul Perea-Causin +2
Fractionalization in ideal Chern bands and non-Hermitian topological physics are two active but so far separate research directions. Merging these, we generalize the notion of idea…
Filling-Sensitive Spectral Complexity from Hilbert-Space Holonomy in Fragmented Non-Hermitian Systems
Jiong-Hao Wang, Maria Zelenayova, Christopher Ekman +1
We show that Hilbert-space holonomy provides a geometric organizing principle for spectral reality in fragmented non-Hermitian many-body systems, complementary to conventional symm…
Observation of topological phases without crystalline counterparts
Mou Yan, Yu-Liang Tao, Yichong Hu +4
Topological phases have been extensively studied primarily in crystalline systems with translational symmetry. Recent theoretical studies, however, have demonstrated the existence…
Transitions from Composite Fermi Liquid to Moore-Read States in Weyl Semimetals
Jiong-Hao Wang, Yong Xu
Weyl semimetals represent a significant class of topological gapless materials in three dimensions and have been shown to exhibit three-dimensional quantum Hall effect. However, ex…
Three-Dimensional Quantum Hall Effect in Topological Amorphous Metals
Jiong-Hao Wang, Yong Xu
Weyl semimetals have been theoretically predicted to become topological metals with anomalous Hall conductivity in amorphous systems. However, measuring the anomalous Hall conducti…
