Possible Realization of Optical Quadratic and Dirac Points in Woodpile Photonic Crystals
Hai-Xiao Wang, Yige Chen, Guang-Yu Guo +2
The simulation of fermionic relativistic physics, e.g., Dirac and Weyl physics, has led to the discovery of many unprecedented phenomena in photonics, of which the optical-frequenc…
Helical Majorana fermions at the interface of Weyl semimetal and d-wave superconductor: Application to Iridates and high-Tc Cuprates
Yige Chen, Hae-Young Kee
Majorana bound states exist inside a core of half-quantum vortex in spin-triplet superconductors. Despite intense efforts, they have not been discovered in any spin-triplet superco…
Elemental topological Dirac semimetal: α-Sn on InSb(111)
Cai-Zhi Xu, Yang-Hao Chan, Yige Chen +12
Three-dimensional (3D) topological Dirac semimetals (TDSs) are rare but important as a versatile platform for exploring exotic electronic properties and topological phase transitio…
Type-II Dirac Photons
Hai-Xiao Wang, Yige Chen, Zhi Hong Hang +2
The Dirac equation for relativistic electron waves is the parent model for Weyl and Majorana fermions as well as topological insulators. Simulation of Dirac physics in three-dimens…
3D Topological Nodes in Nonsymmorphic Photonic Crystals: Ultrastrong Coupling and Anomalous Refraction
Hai-Xiao Wang, Yige Chen, Zhi Hong Hang +2
We propose to simulate 3D Dirac points and line-nodes with nontrivial topology in nonsymmorphic all-dielectric photonic-crystals with space-time reversal symmetry, which can…
Topological crystalline semimetals in non-symmorphic lattices
Yige Chen, Heung-Sik Kim, Hae-Young Kee
Numerous efforts have been devoted to reveal exotic semimetallic phases with topologically non-trivial bulk and/or surface states in materials with strong spin-orbit coupling. In p…
Topological nodal line semimetals with and without spin-orbital coupling
Chen Fang, Yige Chen, Hae-Young Kee +1
We theoretically study three-dimensional topological semimetals (TSMs) with nodal lines protected by crystalline symmetries. Compared with TSMs with point nodes, e.g., Weyl semimet…
Surface States of Perovskite Iridates AIrO; Signatures of Topological Crystalline Metal with Nontrivial Index
Heung-Sik Kim, Yige Chen, Hae-Young Kee
There have been increasing efforts in realizing topological metallic phases with nontrivial surface states. It was suggested that orthorhombic perovskite iridates are classified as…
Topological Crystalline Metal in Orthorhombic Perovskite Iridates
Yige Chen, Yuan-Ming Lu, Hae-Young Kee
Since topological insulators were theoretically predicted and experimentally observed in semiconductors with strong spin-orbit coupling, more and more attention has been drawn to t…
Topological phases in Iridium oxide superlattices: quantized anomalous charge or valley Hall insulators
Yige Chen, Hae-Young Kee
We study topological phases in Iridium (Ir) oxide superlattices of orthorhombic perovskite-type grown along the [001] crystallographic axis. Due to strong spin-orbit coupling of Ir…
Reply to Comment by Vanderbilt, Souza and Haldane: arXiv:1312.4200
Y. Chen, D. L. Bergman, A. A. Burkov
We reassert our statement that the non-quantized Weyl node contribution to the anomalous Hall conductivity is not a Fermi surface property, contrary to the claim by Vanderbilt, Sou…
Axion response in Weyl semimetals
Y. Chen, Si Wu, A. A. Burkov
Weyl semimetal is a new phase of matter that provides the first solid state realization of chiral Weyl fermions. Most of its unique physics is a consequence of chiral anomaly, name…
Weyl fermions and the anomalous Hall effect in metallic ferromagnets
Y. Chen, D. L. Bergman, A. A. Burkov
We reconsider the problem of the anomalous Hall effect in ferromagnetic SrRuO, incorporating insights from the recently developed theory of Weyl semimetals. We demonstrate that…
