Here we report the observation of bulk superconductivity in single crystals of the two-dimensional kagome metal KV$_3$Sb$_5$. Magnetic susceptibility, resistivity, and heat capacity measurements reveal superconductivity below $T_c = 0.93$K, and density functional theory (DFT) calculations further characterize the normal state as a $\mathbb{Z}_2$ topological metal. Our results demonstrate that the recent observation of superconductivity within the related kagome metal CsV$_3$Sb$_5$ is likely a…

Charge Density Waves and Electronic Properties of Superconducting Kagome Metals.
The inverse Star of David deformation is revealed as the 2×2×2 CDW ground state of the kagome lattice and the electron-phonon coupling is too weak to account for the superconductivity T_{c} in all three materials.

Proximity-induced spin-triplet superconductivity and edge supercurrent in the topological Kagome metal, $\mathrm{K_{1-x}V_3Sb_5}$
Materials with transition metals in triangular lattices are of great interest for their potential combination of exotic magnetism and electronic topology. Kagome nets, also known as trihexagonal, are
Competing electronic orders on kagome lattices at van Hove filling
The electronic orders in Hubbard models on a kagome lattice at van Hove filling are of intense current interest and debate. We study this issue using the singular-mode functional renormalization
Topological Superconductivity on the Surface of Fe-Based Superconductors.
It is shown that the surface TSC phase only exists up to a certain bulk pairing gap, and there is a normal-topological phase transition driven by the temperature, which has not been discussed before.
Topological insulators with inversion symmetry
Topological insulators are materials with a bulk excitation gap generated by the spin-orbit interaction that are different from conventional insulators. This distinction is characterized by ${Z}_{2}$

A Chern-Simons theory for the doped spin-1/2 kagome system is constructed, from which it is shown that the system is an exotic superconductor that breaks time-reversal symmetry. It is also shown that
Elaboration of the α-model derived from the BCS theory of superconductivity
The single-band α-model of superconductivity (Padamsee et al 1973 J. Low Temp. Phys. 12 387) is a popular model that was adapted from the single-band Bardeen–Cooper–Schrieffer (BCS) theory of
