Possible pairing symmetry in the FeSe-based superconductors determined by quasiparticle interference
Yi Gao, Yuting Wang, Tao Zhou +2
We study the momentum-integrated quasiparticle interference (QPI) in the FeSe-based superconductors. This method was recently proposed theoretically and has been applied to determi…
Proximity-Induced Superconductivity with Subgap Anomaly in Type II Weyl Semi-Metal WTe2
Qiao Li, Chaocheng He, Yaojia Wang +16
Due to the non-trivial topological band structure in type-II Weyl semimetal Tungsten ditelluride (WTe2), unconventional properties may emerge in its superconducting phase. While re…
Direct visualization of sign reversal s^+- superconducting gaps in FeTe0.55Se0.45
Mingyang Chen, Qingkun Tang, Xiaoyu Chen +7
In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi su…
Directly visualizing the sign change of d-wave superconducting gap in Bi2Sr2CaCu2O8+δ by phase-referenced quasiparticle interference
Qiangqiang Gu, Siyuan Wan, Qingkun Tang +7
The superconducting state is achieved by the condensation of Cooper pairs and is protected by the superconducting gap. The pairing interaction between the two electrons of a Cooper…
Critical exponents of nonlinear sigma model on Grassmann manifold by expansion
Shan-Yue Wang, Da Wang, Qiang-Hua Wang
Motivated by the numerical evidence of a continuous phase transition between antiferromagnetic and paramagnetic phases in the half-filled SU(N) Hubbbard model, we studied its low e…
Entanglement in a second order topological insulator on a square lattice
Qiang Wang, Da Wang, Qiang-Hua Wang
In a -dimensional topological insulator of order , there are zero energy states on its corners which have close relationship with its entanglement behaviors. We studied the b…
Theory of chiral -wave superconductivity with near-nodes for SrRuO
Wan-Sheng Wang, Cong-Cong Zhang, Fu-Chun Zhang +1
We use functional renormalization group method to study a three-orbital model for superconducting SrRuO. Although the pairing symmetry is found to be chiral -wave, the a…
Robust and clean Majorana zero mode in the vortex core of high-temperature superconductor (Li0.84Fe0.16)OHFeSe
Q. Liu, C. Chen, T. Zhang +13
The Majorana fermion, which is its own anti-particle and obeys non-abelian statistics, plays a critical role in topological quantum computing. It can be realized as a bound state a…

Shuang Liang, Minghong Jiang, Wei Chen +2
We study the Kitaev spin liquid (KSL) in a [001] magnetic field employing the mean field theory (MFT/MF) in the Majorana fermion representation. The MF Hamiltonian of the system ha…
Visualizing the -vector in a nematic triplet superconductor
Wei-Cheng Bao, Qing-Kun Tang, Da-Chuan Lu +1
Recent experiments show strong evidences of nematic triplet superconductivity in doped BiSe and in BiTe thin film on a superconducting substrate, but with varying i…
Direct visualization of the nematic superconductivity in CuBiSe
Ran Tao, Ya-Jun Yan, Xi Liu +5
CuBiSe hosts both topological surface states and bulk superconductivity. It has been identified recently as a topological superconductor (TSC) with an extraordinary nem…
Response and phase transition of a Kitaev spin liquid in a local magnetic field
Shuang Liang, Bosen He, Zhaoyang Dong +3
We study the response of the Kitaev spin liquid (KSL) to a local magnetic field perpendicular to the Kitaev honeycomb lattice. The local magnetic field induces a dynamical excitati…
