Kondo Signatures of a Quantum Magnetic Impurity in Topological Superconductors
Rui Wang, W. Su, Jian-Xin Zhu +5
We study the Kondo physics of a quantum magnetic impurity in two-dimensional topological superconductors (TSCs), either intrinsic or induced on the surface of a bulk topological in…
Searching for two-dimensional Weyl superconductors in heterostructures
Lei Hao, C. S. Ting
Two-dimensional Weyl superconductor is the most elusive member of a group of materials with Weyl fermions as low-energy excitations. Here, we propose to realize this state in a het…
Topological Phase Transitions and a Two-Dimensional Weyl Superconductor in a Half-Metal/Superconductor Heterostructure
Lei Hao, C. S. Ting
We find a series of topological phase transitions in a half-metal/superconductor heterostructure, by tuning the direction of the magnetization of the half-metal film. These include…
Spinon Majorana fermions
Rui Wang, Hong-Yan Lu, Baigeng Wang +1
A realization of Majorana fermions is proposed in the frustrated magnets via the topological proximity effect. Specifically, we consider a theoretical model, where a topological in…
Type-II Topological Meissner States
Chun Chen, Wei Yan, C. S. Ting +1
We study the \emph{orbital effects} of the synthetic magnetic fields in an interacting square lattice two-leg fermionic ladder model with the number-conserving pair hopping that ho…
Ferromagnetism and superconductivity with possible pairing symmetry in partially hydrogenated graphene
Hong-Yan Lu, Lei Hao, Rui Wang +1
By means of first-principles calculations, we predict two new types of partially hydrogenated graphene systems: CH and CH, which are shown to be ferromagnet…
Tunneling interstitial impurity in iron-chalcogenide based superconductors
Huaixiang Huang, Degang Zhang, Yi Gao +2
A pronounced local in-gap zero-energy bound state (ZBS) has been observed by recent scanning tunneling microscopy (STM) experiments on the interstitial Fe impurity (IFI) and its ne…
Edge states and local electronic structure around an adsorbed impurity in a topological superconductor
Yuan-Yen Tai, Hongchul Choi, Towfiq Ahmed +2
Recently topological superconducting states has attracted a lot of interest. In this work, we consider a topo- logical superconductor with topological mirror order [1] and s$…
A unified description of superconducting pairing symmetry in electron-doped Fe-based-122 compounds
Bo Li, Lihua Pan, Yuan-Yen Tai +4
The pairing symmetry is examined in highly electron-doped Ba(FeCoAs) and AFeSe (with A=K, Cs) compounds, with similar crystallographic and electronic ba…
Evolution of the Fermi surface topology in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on the minimum two-orbital model and the phase diagram recently proposed by Tai et al.\ (Europhys. Lett. \textbf{103}, 67001(2013)) for both electron- and hole-doped 122 iron…
Magnetic domain walls induced by twin boundaries in low doped Fe-pnictides
Bo Li, Jian Li, Kevin E Bassler +1
Inspired by experimental observations of the enhancement of superconductivity at the twin-boundary (TB) in slightly electron doped Ba(Ca)(FeAs) where a strong antife…
Interaction-induced localization of fermionic mobile impurities in a Larkin-Ovchinnikov superfluid
Jian Li, Jin An, C. S. Ting
We theoretically investigate the interplay between the fermionic mobile impurity atoms and a Larkin-Ovchinnikov (LO) superfluid in a two dimensional optical lattice. We find that t…
Impact of Step Defects on Surface States of Topological Insulators
Degang Zhang, C. S. Ting
The eigenstates in the presence of a step defect (SD) along or y axis on the surface of topological insulators are exactly solved. It is shown that unlike the electronic states…

Based on a phenomenological model with competing spin-density-wave (SDW) and extended wave superconductivity, the vortex states in BaKFeAs are investi…
Model for Tunneling-mediated Impurity Resonances in Bilayer Cuprate Superconductors
Degang Zhang, C. S. Ting
We have studied tunneling-mediated local density of states (LDOS) of the surface layer of a bilayer cuprate, where a Zn impurity is located on the second Cu-O layer. When the tunne…
