Superconductivity in the Z2 kagome metal KV3Sb5

Brenden R. Ortiz et al.

Summary: This study reports the observation of bulk superconductivity in single crystals of the two-dimensional kagome metal KV3Sb5, with further characterization of the normal state as a Z(2) topological metal using density functional theory (DFT) calculations. The presence of superconductivity in the AV(3)Sb(5) (A: K, Rb, Cs) family of compounds suggests a common feature across these materials, establishing them as a rich arena for studying the interplay between bulk superconductivity, topological surface states, and likely electronic density wave order in an exfoliable kagome lattice.

Superconductivity and Normal-State Properties of Kagome Metal RbV3Sb5 Single Crystals

Qiangwei Yin et al.

Summary: The discovery of superconductivity in RbV3Sb5 single crystals with V kagome lattice is reported, showing a superconducting transition at around 0.92K. Anomalies in properties at T* around 102-103K are observed, possibly linked to the formation of a charge ordering state. The drastic change and sign reversal of the Hall coefficient R-H at T* can be partially explained by enhanced mobility of hole-type carriers, with quantum oscillations indicating the presence of small Fermi surfaces with low effective mass.

Nodeless kagome superconductivity in LaRu3Si2

C. Mielke et al.

Summary: LaRu3Si2, a kagome superconductor with a critical temperature around 7K, exhibits nodeless moderate coupling superconductivity with a single s-wave gap that is robust against hydrostatic pressure up to 2 GPa. The calculated normal state band structure features a kagome flat band, Dirac and van Hove points near the Fermi level formed by Ru-dz(2) orbitals. Additionally, electron-phonon coupling alone cannot reproduce a significant portion of the critical temperature, suggesting other factors enhance Tc in LaRu3Si2.

Unconventional chiral charge order in kagome superconductor KV3Sb5

Yu-Xiao Jiang et al.

Summary: The study reveals an unconventional chiral charge order in KV3Sb5, a material with both a topological band structure and a superconducting ground state, using high-resolution scanning tunnelling microscopy. A 2 x 2 superlattice structure is observed in the experiment, along with an energy gap opening and charge modulation across the Fermi level.

Concurrence of anomalous Hall effect and charge density wave in a superconducting topological kagome metal

F. H. Yu et al.

Summary: A giant anomalous Hall effect (AHE) has been observed in kagome superconductor CsV3Sb5, with a conductivity reaching up to 2.1 x 10(4)Ω⁻¹ cm⁻¹, larger than most ferromagnetic metals. The emergence of AHE is strongly correlated with the higher-temperature charge-density-wave (CDW) transition, and AHE disappears when the CDW transition is completely suppressed under high pressure.

Probing topological quantum matter with scanning tunnelling microscopy

Jia-Xin Yin et al.

Summary: The search for topological phases of matter is moving towards strongly interacting systems like magnets and superconductors. Scanning tunnelling microscopy has become a powerful tool for probing and discovering emergent topological matter, with potential for providing new insights into topological matter at the atomic level in the future.
