Point-Gap Bound States in Non-Hermitian Systems
Zixi Fang, Chen Fang, Kai Zhang
In this paper, we systematically investigate the impurity-induced bound states in 1D non-Hermitian systems. By establishing an exact relationship between impurity potential and bou…
Diversified Ruderman-Kittel-Kasuya-Yosida Interactions in a Nonsymmorphic Crystal
Zhongyi Zhang, Shengshan Qin, Chen Fang +2
We show that there are diversified Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions between magnetic impurities, mediated by itinerant electrons, in a centrosymmetric crystal resp…
Spin-triplet Superconductivity in Nonsymmorphic crystals
Shengshan Qin, Chen Fang, Fu-chun Zhang +1
Spin-triplet superconductivity is known to be a rare quantum phenomenon. Here we show that nonsymmorphic crystalline symmetries can dramatically assist spin-triplet superconductivi…
Topological Superconductivity from Unconventional Band Degeneracy with Conventional Pairing
Zhongyi Zhang, Zhenfei Wu, Chen Fang +4
We present a new scheme for Majorana modes in systems with nonsymmporhic-symmetry-protected band degeneracy. We reveal that when the gapless fermionic excitations are encoded with…
Chern numbers of topological phonon band crossing determined with inelastic neutron scattering
Zhendong Jin, Biaoyan Hu, Yiran Liu +13
Topological invariants in the band structure, such as Chern numbers, are crucial for the classification of topological matters and dictate the occurrence of exotic properties, yet…
Magnetic molecular orbitals in MnSi
Zhendong Jin, Yangmu Li, Zhigang Hu +15
A large body of knowledge about magnetism is attained from models of interacting spins, which usually reside on magnetic ions. Proposals beyond the ionic picture are uncommon and s…
