We report the structure and physical properties of two newly discovered compounds AV8Sb12 and AV6Sb6 (A = Cs, Rb), which have C 2 (space group: Cmmm) and C 3 (space group: R3¯m ) symmetry, respectively. The basic V-kagome unit appears in both compounds, but stacking differently. A V2Sb2 layer is sandwiched between two V3Sb5 layers in AV8Sb12, altering the V-kagome lattice and lowering the symmetry of kagome layer from hexagonal to orthorhombic. In AV6Sb6, the building block is a more complex… 


Unusual competition of superconductivity and charge-density-wave state in a compressed topological kagome metal
High-pressure electrical transport and magnetic susceptibility measurements to study CsV3Sb5 with the highest Tc of 2.7 K indicate an unusual competition between superconductivity and CDW state in pressurized kagome lattice.
Giant anomalous Hall angle in a half-metallic magnetic Weyl semimetal
Magnetic Weyl semimetals (WSMs) with time reversal symmetry breaking exhibit Weyl nodes that act as monopoles of Berry curvature and are thus expected to generate a large intrinsic anomalous Hall

CsV3 Sb5 is a new platform for exploring the interplay between superconductivity and CDW in topological kagome metals and indicates the competing inter play between CDW and superconducting state in this material.
Quantum-limit Chern topological magnetism in TbMn6Sn6
Scanning tunnelling microscopy is used to reveal a new topological kagome magnet with an intrinsic Chern quantum phase, which shows a distinct Landau fan structure with a large Chern gap, and the realization of a quantum-limit Chern phase in TbMn6Sn6 is point to.
Efficiency of ab-initio total energy calculations for metals and semiconductors using a plane-wave basis set
We present a detailed description and comparison of algorithms for performing ab-initio quantum-mechanical calculations using pseudopotentials and a plane-wave basis set. We will discuss: (a) partial
Giant, unconventional anomalous Hall effect in the metallic frustrated magnet candidate, KV3Sb5.
KV3Sb5 shows enhanced skew scattering that scales quadratically, not linearly, with the longitudinal conductivity, possibly arising from the combination of highly conductive Dirac quasiparticles with a frustrated magnetic sublattice, which allows the possibility of reaching an anomalous Hall angle of 90° in metals.
Large anomalous Hall effect in a non-collinear antiferromagnet at room temperature
Empirical evidence is reported for a large anomalous Hall effect in an antiferromagnet that has vanishingly small magnetization, which could be useful for various applications including spintronics—for example, to develop a memory device that produces almost no perturbing stray fields.
I and i
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Apesar da gestão de carreiras ser uma preocupação recente no quadro da gestão das relações de trabalho, é hoje evidente a crise em que se encontra a forma tradicional de abordagem desta problemática.
Cascade of correlated electron states in a kagome superconductor CsV3Sb5.
A cascade of different symmetry-broken electronic states as a function of temperature in a new kagome superconductor, CsV3Sb5, is discovered, which provides intriguing parallels to high-Tc superconductors and twisted bilayer graphene.
