Query: Chiral charge order in the superconductor 2H-TaS2   We find chiral charge order in the superconductor 2H-TaS2 using Scanning
Tunneling Microscopy and Spectroscopy (STM/S) at 0.1 K. Topographic images show
hexagonal atomic lattice and charge density wave (CDW) with clockwise and
counterclockwise charge modulations. Tunneling spectroscopy reveals the
superconducting density of states, disappearing at Tc = 1.75 K and showing a
wide distribution of values of the superconducting gap, centered around
\Delta=0.28 meV.
