Unconventional gapping behavior in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Eun Sang Choi +19
Determining the types of superconducting order in quantum materials is a challenge, especially when multiple degrees of freedom, such as bands or orbitals, contribute to the fermio…
Interlayer Charge-density-wave Vector Phase Induced Structural Chirality
Sen Shao, Wei-Chi Chiu, Tao Hou +21
Chiral charge density waves (CDWs) have attracted intense interest due to their exotic quantum properties, yet the microscopic origin of structural chirality emerging from correlat…
Discovery of terahertz-frequency orbitally-coupled magnons in a kagome ferromagnet
Mengqian Che, Weizhao Chen, Maoyuan Wang +12
In ferromagnetic materials, magnons - quanta of spin waves - typically resonate in the gigahertz range. Beyond conventional magnons, while theoretical studies have predicted magnon…
Evidence chain for time-reversal symmetry-breaking kagome superconductivity
Hanbin Deng, Guowei Liu, Z. Guguchia +25
Superconductivity and magnetism are antagonistic quantum matter, while their intertwining has long been considered in frustrated-lattice systems1-3. In this work, we utilize scanni…
Chiral kagome superconductivity modulations with residual Fermi arcs in KV3Sb5 and CsV3Sb5
Hanbin Deng, Hailang Qin, Guowei Liu +26
Superconductivity involving finite momentum pairing can lead to spatial gap and pair density modulations, as well as Bogoliubov Fermi states within the superconducting gap. However…
Magnetoresistance hysteresis in the superconduting state of Kagome CsVSb
Tian Le, Jinjin Liu, Zhiwei Wang +1
The hysteresis of magnetoresistance observed in superconductors is of great interest due to its potential connection with unconventional superconductivity. In this study, we perfor…
Local pairing versus bulk superconductivity intertwined by the charge density wave order in Cs(VTa)Sb
Jinyulin Li, Qing Li, Jinjin Liu +5
There is a common belief that superconductivity and charge density wave (CDW) order accommodate homogenously in real space but compete with each other for the effective density of…
Strong-coupling superconductivity and weak vortex pinning in Ta-doped CsVSb single crystals
Jinyulin Li, Wei Xie, Jinjin Liu +6
By measuring magnetizations of pristine and Ta-doped CsVSb single crystals, we have carried out systematic studies on the lower critical field, critical current density…
Observation of Fermi-surface-dependent anisotropic Cooper pairing in kagome superconductor CsV3Sb5
Akifumi Mine, Yigui Zhong, Jinjin Liu +9
In the recently discovered kagome superconductor AV3Sb5 (A = K, Rb, and Cs), superconductivity is intertwined with an unconventional charge density wave order. The pairing symmetry…
Orbital Magneto-Nonlinear Anomalous Hall Effect in Kagome Magnet FeSn
Lujunyu Wang, Jiaojiao Zhu, Haiyun Chen +14
It has been theoretically predicted that perturbation of the Berry curvature by electromagnetic fields gives rise to intrinsic nonlinear anomalous Hall effects that are independent…
Conventional Superconductivity in the Doped Kagome Superconductor Cs(V0.86Ta0.14)3Sb5 from Vortex Lattice Studies
Yaofeng Xie, Nathan Chalus, Zhiwei Wang +8
A hallmark of unconventional superconductors is their complex electronic phase diagrams where "intertwined orders" of charge-spin-lattice degrees of freedom compete and coexist as…
Tunable vortex bound states in multiband CsV3Sb5-derived kagome superconductors
Zihao Huang, Xianghe Han, Zhen Zhao +12
Vortices and bound states offer an effective means of comprehending the electronic properties of superconductors. Recently, surface dependent vortex core states have been observed…
