The electronic structure shows multi-orbital nature and possible three-dimensional character. An anomalous temperature-dependent spectral weight redistribution and broad lineshape indicate the incoherent nature of the spectral function. At the density-wave-like transition temperature around 200 K, a partial gap opens at the Fermi patches. These findings suggest that BaTi2As2O is likely a charge density wave materia","authors_text":"B. P. Xie, D. H. Lu, D. L. Feng, F. Qin, H. C. Xu, J. J. Ying, K. Shimada, M. Arita, M. Taniguchi, M.
