Doping dependence of the charge-density-wave order in HgBa$_{2}$CuO$_{4+\delta}$

Following the original discovery of short-range charge-density-wave (CDW) order in the orthorhombic double-layer cuprate YBa$_{2}$Cu$_{3}$O$_{6+\delta}$ (YBCO) below optimal doping, resonant X-ray scattering measurements have revealed that the simple tetragonal single-layer compound HgBa$_{2}$CuO$_{4+\delta}$ (Hg1201; Tc = 71 K) exhibits short-range CDW order as well [1]. Here we report on the doping dependence of the CDW order in Hg1201 and contrast our results with the extensive data available for YBCO [2]. Work done in collaboration with: W. Tabis, G. Yu, M.J.
