英文摘要	We study Aharonov-Bohm (AB) oscillations in the local density of states (LDOS) for topological insulator (TI) and conventional metal Au(111) surfaces with spin-orbit interaction, which can be probed by spin-polarized scanning tunneling microscopy. We show that the spacial AB oscillatory period in the total LDOS is a flux quantum Phi(0) = hc/e (weak localization) in both systems. Remarkably, an analogous weak antilocalization with Phi(0)/2 periodic spacial AB oscillations in spin components of LDOS for TI surface is observed, while it is absent in Au(111).
