Effect of anisotropic impurity scattering in d-wave superconductors
Ze-Long Wang, Rui-Ying Mao, Da Wang +1
In d-wave superconductors, the effect of s-wave point disorder has been extensively studied in the literature. In this work, we study the anisotropic disorder with a th…
Symmetry Constraints on Direct-Current Josephson Diodes
Da Wang, Qiang-Hua Wang, Congjun Wu
It is necessary to break both time-reversal and parity symmetries to realize a Josephson, or superconducting, diode exhibiting nonreciprocal critical direct-currents (DC). In fact,…
Reply to "Comment on 'Anisotropic Scattering Caused by Apical Oxygen Vacancies in Thin Films of Overdoped High Temperature Cuprate Superconductors'"
Da Wang, Jun-Qi Xu, Hai-Jun Zhang +1
In our recent work [Phys. Rev. Lett. 128, 137001 (2002)], we proposed that the apical oxygen vacancies act as anisotropic scattering impurities. Within the Born approximation, this…
Magnetotransport in overdoped LaSrCuO: Effect of anisotropic scattering
Rui-Ying Mao, Da Wang, Qiang-Hua Wang
We revisit the Hall effect and magnetoresistivity by incorporating the anisotropic scattering caused by apical oxygen vacancies in overdoped La-based cuprates. The theoretical calc…
Anisotropic scattering caused by apical oxygen vacancies in thin films of overdoped high-temperature cuprate superconductors
Da Wang, Jun-Qi Xu, Hai-Jun Zhang +1
There is a hot debate on the anomalous behavior of superfluid density in overdoped LaSrCuO films in recent years. The linear drop of at low temperatures…
Possible two-component spin-singlet pairings in Sr2RuO4
San-Jun Zhang, Da Wang, Qiang-Hua Wang
Recent experiments suggest a multi-component pairing function in Sr2RuO4, which appears to be inconsistent with the absence of an apparent cusp in the transition temperature (Tc) a…
Magnetotransport in overdoped LaSrCuO: a Fermi liquid approach
Rui-Ying Mao, Da Wang, Congjun Wu +1
Recently, several experiments on LaSrCuO (LSCO) challenged the Fermi liquid picture for overdoped cuprates, and stimulated intensive debates [1]. In this work, we s…
Anomalous isotope effect in BCS superconductors with two boson modes
Gan Sun, Pan-Xiao Lou, Sheng-Qiang Lai +2
The isotope effect in the superconducting transition temperature is anomalous if the isotope coefficient or . In this work, we show that such anomalous behaviors can n…
Superconductivity, pair density wave, and Neel order in cuprates
Li-Han Chen, Da Wang, Yi Zhou +1
We investigate in underdoped cuprates possible coexistence of the superconducting (SC) order at zero momentum and pair density wave (PDW) at momentum in the presen…
Chiral and helical -wave superconductivity in doped bilayer BiH
L. Yang, W. S. Wang, D. Wang +1
We investigate the superconductivity (SC) driven by correlation effects in electron-doped bilayer BiH near a type-II van Hove singularity (vHS). By functional renormalization group…
On Meissner Effect and Superfluid Density in Superconductors
Da Wang
As the most successful microscopic superconductivity theory, Bardeen-Cooper-Schrieffer(BCS) theory has a very peculiar prediction: at zero temperature, only a fraction of electrons…
Spontaneous time-reversal symmetry breaking in the boundary Majorana flat bands
Yi Li, Da Wang, Congjun Wu
We study the boundary Majorana modes for the single component p-wave weak topological superconductors or superfluids, which form zero energy flat bands protected by time-reversal s…
High superconductivity at the FeSe/SrTiO Interface
Fa Wang, Yuan-Yuan Xiang, Da Wang +2
In a recent experiment the superconducting gap of a single unit cell thick FeSe film on SrTiO substrate is observed by scanning tunneling spectroscopy and angle-resolved photoe…
Observation of Lattice and Andreev Bound States of Vortices in Ba0.6K0.4Fe2As2 Single Crystals with Scanning Tunneling Microscopy/Spectroscopy
Lei Shan, Yong-Lei Wang, Bing Shen +9
For a type-II superconductor, when the applied magnetic field is higher than the lower critical value Hc1, the magnetic flux will penetrate into the superconductor and form quantiz…
Theory of tunnelling into a multi-band superconductor: decoherence and interference
Da Wang, Yuan Wan, Qiang-Hua Wang
By an exact formulation of tunnelling into a multi-band superconductor in terms of Green's functions, we demonstrate that the multi-band feature of the iron-based superconductors c…
