Query: Robust Weyl points in a 1D superlattice with transverse spin-orbit
  coupling   Weyl points, synthetic magnetic monopoles in the 3D momentum space, are the
key features of topological Weyl semimetals. The observation of Weyl points in
ultracold atomic gases usually relies on the realization of high-dimensional
spin-orbit coupling (SOC) for two pseudospin states (% \textit{i.e.,}
spin-1/2), which requires complex laser configurations and precise control of
laser parameters, thus has not been realized in experiment. Here we propose
that robust Wely points can be realized using 1D triple-well superlattices
(spin-1/three-band systems) with 2D transverse SOC achieved by Raman-assisted
tunnelings. The presence of the third band is responsible to the robustness of
the Weyl points against system parameters (e.g., Raman laser polarization,
phase, incident angle, etc.). Different from a spin-1/2 system, the non-trivial
topology of Weyl points in such spin-1 system is characterized by both the spin
vector and tensor textures, which can be probed using momentum-resolved Rabi
spectroscopy. Our proposal provides a simple yet powerful platform for
exploring Weyl physics and related high-dimensional topological phenomena using
high pseudospin ultracold atoms.
