Query: Multiband nodeless superconductivity near the charge-density-wave
  quantum critical point in ZrTe3-xSex   Recently it was found that selenium doping can suppress the
charge-density-wave (CDW) order and induce bulk superconductivity in ZrTe$_3$.
The observed superconducting dome suggests the existence of a CDW quantum
critical point (QCP) in ZrTe$_{3-x}$Se$_x$ near $x \approx$ 0.04. To elucidate
its superconducting state near the CDW QCP, we measure the thermal conductivity
of two ZrTe$_{3-x}$Se$_x$ single crystals ($x$ = 0.044 and 0.051) down to 80
mK. For both samples, the residual linear term $\kappa_0/T$ at zero field is
negligible, which is a clear evidence for nodeless superconducting gap.
Furthermore, the field dependence of $\kappa_0/T$ manifests multigap behavior.
These results demonstrate multiple nodeless superconducting gaps in
ZrTe$_{3-x}$Se$_x$, which indicates conventional superconductivity despite of
the existence of a CDW QCP.
