Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

Weyl semimetals are conductors whose low-energy bulk excitations are Weyl fermions,
whereas their surfaces possess metallic Fermi arc surface states. These Fermi arc surface …

The kagome lattice is a two-dimensional network of corner-sharing triangles that is known to
host exotic quantum magnetic states,,. Theoretical work has predicted that kagome lattices …

Three-dimensional topological Weyl semimetals can generally support a zero-dimensional
Weyl point characterized by a quantized Chern number or a one-dimensional Weyl nodal …

In quantum field theory, Weyl fermions are relativistic particles that travel at the speed of light
and strictly obey the celebrated Lorentz symmetry. Their low-energy condensed matter …

A representative class of kagome materials, AV3Sb5 (A= K, Rb, Cs), hosts several
unconventional phases such as superconductivity, Z 2 non-trivial topological states, and …

The recent discovery of a Weyl semimetal in TaAs offers the first Weyl fermion observed in
nature and dramatically broadens the classification of topological phases. However, in TaAs …

The recent proposal of the type-II Weyl semimetal state has attracted significant interest. In
this Letter, we propose the concept of the three-dimensional type-II Dirac fermion and …

Three-dimensional condensed matter incarnations of Weyl fermions generically have a tilted
dispersion—in sharp contrast to their elusive high-energy relatives where a tilt is forbidden …

We report angle resolved photoemission experiments on a newly discovered family of
kagome metals RV 6 Sn 6 (R= Gd, Ho). Intrinsic bulk states and surface states of the …
