Electronic Reconstruction Towards Topological Superconductivity in FeTe
Hongtao Rong, Yang Ge, Zi-Jie Yan +13
The recent discovery of intrinsic superconductivity in stoichiometric FeTe films has renewed interest in the Te-rich end member of the iron chalcogenides for studies of unconventio…
Signatures of nodal superconductivity in stoichiometric FeTe
Cequn Li, Zi-Jie Yan, Yang Ge +13
Superconductivity in stoichiometric FeTe opens access to the FeTe endpoint of the Fe(Se,Te) phase diagram, yet the nature of its superconducting pairing state remains unresolved. I…
Stoichiometric FeTe is a Superconductor

Iron-based superconductors are a fascinating family of materials in which multiple electronic bands and strong antiferromagnetic (AFM) correlations are key ingredients for competin…
Symmetry-enforced Moiré Topology
Yunzhe Liu, Ethan Angerhofer, Kaijie Yang +2
Topological flat bands in two-dimensional (2D) moiré materials have emerged as promising platforms for exploring the interplay between topology and correlation effects. However, re…
Pseudo-gauge Fields in Dirac and Weyl Materials
Jiabin Yu, Chao-Xing Liu
Electrons in low-temperature solids are governed by the non-relativistic Schrdinger equation, since the electron velocities are much slower than the speed of light. Remar…
Dynamical Piezomagnetic Effect in Time-Reversal Invariant Weyl Semimetals with Axionic Charge-Density Waves
Jiabin Yu, Benjamin J. Wieder, Chao-Xing Liu
Charge-density waves (CDWs) in Weyl semimetals (WSMs) have been shown to induce an exotic axionic insulating phase in which the sliding mode (phason) of the CDW acts as a dynamical…

Gapless Criterion for Crystals from Effective Axion Field
Jiabin Yu, Zhi-Da Song, Chao-Xing Liu
Gapless criteria that can efficiently determine whether a crystal is gapless or not are particularly useful for identifying topological semimetals. In this work, we propose a suffi…
Piezoelectricity and Topological Quantum Phase Transitions in Two-Dimensional Spin-Orbit Coupled Crystals with Time-Reversal Symmetry
