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.

Chiral flux phase in the Kagome superconductor AV3Sb5

Xilin Feng et al.

Summary: The study identifies a chiral flux phase in the quasi-2D Kagome superconductor AV(3)Sb(5), which has the lowest energy and exhibits 2 x 2 charge orders observed experimentally. This phase breaks time-reversal symmetry and displays anomalous Hall effect.

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.

Double Superconducting Dome and Triple Enhancement of Tc in the Kagome Superconductor CsV3Sb5 under High Pressure

K. Y. Chen et al.

Summary: The study reveals that the CDW transition in CsV3Sb5 decreases with pressure, with an unusual M-shaped double dome in the T-c(P) curve showing enhancement up to 8 K at 2 GPa. This indicates a strong competition between CDW-like order and SC, particularly in the intermediate pressure range of P-c1 <= P <= P-c2.

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.

Pressure-induced reemergence of superconductivity in the topological kagome metal CsV3Sb5

Zhuyi Zhang et al.

Summary: This study reports pressure-induced reemergence of superconductivity in CsV3Sb5, where the superconducting critical temperature initially increases and then decreases with pressure, forming a dome-shaped superconducting phase diagram. A new superconducting state emerges with further compression above 16.5 GPa, with T-c reaching a second maximum around 5.0 K and remaining stable up to 47.9 GPa. The reemergence of superconductivity in V-based superconductor is suggested to be attributed to a pressure-induced Lifshitz transition, supported by high-pressure synchrotron x-ray-diffraction measurements showing the stability of the pristine hexagonal phase up to 43.1 GPa.

Doping the chiral spin liquid: Topological superconductor or chiral metal

Xue-Yang Song et al.

Summary: There are two different chiral spin liquid states on the triangular lattice, labeled CSL1 and CSL2, associated with distinct topological orders. While both states break time reversal symmetry and exhibit the same quantized spin Hall conductance, doping can lead to different scenarios - CSL1 may become a chiral metal while CSL2 may form a d+id superconductor. The complex relation between topological superconductors, chiral spin liquids, and quantum criticality is clarified through these different scenarios.
