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…
Thermomodulated intrinsic Josephson effect in Kagome CsV3Sb5
Tian Le, Zhuokai Xu, Jinjin Liu +3
Superconducting chiral domains associated with a time-reversal symmetry-breaking order parameter have garnered significant attention in Kagome systems. In this work, we demonstrate…
Discovery of a topological exciton insulator with tunable momentum order
Md Shafayat Hossain, Tyler A. Cochran, Yu-Xiao Jiang +27
Correlated topological materials often maintain a delicate balance among physical symmetries: many topological orders are symmetry protected, while most correlated phenomena arise…
Field induced density wave in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Julian Ingham +19
On the kagome lattice, electrons benefit from the simultaneous presence of band topology, flat electronic bands, and van Hove singularities, forming competing or cooperating orders…
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…
