Observation of warping effects in the band and angular momentum structures of topological insulator Bi2Te3
Wonsig Jung, Yeongkwan Kim, Beomyoung Kim +10
We performed angle resolved photoemission (ARPES) experiments on Bi2Te3 with circularly polarized light. ARPES data show very strong circular dichroism, indicating existence of orb…
Detecting Chiral Orbital Angular Momentum by Circular Dichroism ARPES
Jin-Hong Park, Choong H. Kim, Jun Won Rhim +1
We show, by way of tight-binding and first-principles calculations, that a one-to-one correspondence between electron's crystal momentum k and non-zero orbital angular momentum (OA…
Emergence of Orbital Angular Momentum by Inversion Symmetry Breaking and Its Detection by ARPES
Choong H. Kim, Jin-Hong Park, Jun Won Rhim +8
Rashba-split surface band is characterized by a one-to-one correspondence between the electron's momentum k and its spin orientation. Here we show that a similar correspondence bet…
