Massive 1D Dirac Line, Solitons and Reversible Manipulation on the Surface of a Prototype Obstructed Atomic Insulator, Silicon
Zhongkai Liu, Peng Deng, Yuanfeng Xu +16
Topologically trivial insulators can be classified into atomic insulators (AIs) and obstructed atomic insulators (OAIs) depending on whether the Wannier charge centers are localize…
Anatomy of anomalous Hall effect due to magnetic fluctuations
Ola Kenji Forslund, Xiaoxiong Liu, Soohyeon Shin +16
The anomalous Hall {\color{black} e}ffect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Abs…
Topological Weyl Altermagnetism in CrSb
Cong Li, Mengli Hu, Zhilin Li +12
Altermagnets constitute a novel, third fundamental class of collinear magnetic ordered materials, alongside with ferro- and antiferromagnets. They share with conventional antiferro…
Enhanced Screening in Epitaxial Graphene via Nearly Free-Electron Metal Intercalation
Cedric Schmitt, Lukas Gehrig, Jonas Erhardt +8
Graphene exhibits extraordinarily high carrier mobility, making it a promising platform for next-generation electronics. Scalable growth on SiC, however, suffers from limited diele…
Marginal-Fermi-Liquid-like Behavior without Pseudogap in Infinite-Layer Nickelates
Yu Fan, Zhitong An, Xiang Ding +10
Pseudogap formation, strange-metal behavior and unconventional superconductivity are closely intertwined in hole-doped cuprates, yet their relationship remains unresolved. Infinite…
A novel artificial condensed matter lattice and a new platform for one-dimensional topological phases
Ilya Belopolski, Su-Yang Xu, Nikesh Koirala +22
Engineered lattices in condensed matter physics, such as cold atom optical lattices or photonic crystals, can have fundamentally different properties from naturally-occurring elect…
