Query: Role of CDW fluctuations on the spectral function in a metallic CDW
  system   Angle-resolved photoemission spectroscopy of ZrTe3 has been performed from
room temperature(T) down to 6 K (across Tcdw = 63K) to study the
charge-density-wave (CDW) fluctuation effects in a metallic CDW compound having
Fermi surface (FS) sheets with differing dimensionality. While spectra on the
3-dimensional(D) FS show typical Fermi-Dirac function-like T-dependence, those
along the quasi 1-D FS show formation of a pseudogap, starting at a much higher
T than Tcdw. Simultaneously, a van-Hove singularity consisting of the quasi 1D
FS intersecting the 3D FS shows increase of coherence. This demonstrates the
role of CDW fluctuations on the spectral function, and relation to the
dimensionality of the states, in a metallic CDW system.
