#### Abstract

Author(s): C. N. Kuo, D. Shen, B. S. Li, Nguyen Nhat Quyen, W. Y. Tzeng, C. W. Luo, L. M. Wang, Y. K. Kuo, and C. S. Lue In order to elucidate the charge density wave (CDW) nature in ${\mathrm{LaAuSb}}_{2}$, we have carried out the electrical resistivity, Hall coefficient, Seebeck coefficient, thermal conductivity, as well as ultrafast pump-probe spectroscopy measurements on single crystalline ${\mathrm{LaAuSb}}_{2}$....
