(a)–(c) TrARPES maps of Bi\(_2\)Te\(_3\) along the \(\bar{\Gamma }\bar{K}\) for selected pump-probe delays: (a) negative (unperturbed), (b) \(+0.25\) ps, (c) \(+1\) ps. Inset (a) shows the LEED pattern. Panels (d) and (e) show the circular dichroism (CD) corresponding to the same delays of panels (b) and (c), respectively.
