Unexpected Zero Bias Conductance Peak on the Topological Semimetal Sb(111) with a Broken Bilayer
Yau-Chuen Yam, Shiang Fang, Pengcheng Chen +9
The long-sought Majorana fermion is expected to manifest in a topological-superconductor heterostructure as a zero bias conductance peak (ZBCP). As one promising platform for such…
Selective scattering between Floquet-Bloch and Volkov states in a topological insulator
Fahad Mahmood, Ching-Kit Chan, Zhanybek Alpichshev +4
The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter. The strong time periodic potential of intense laser light can…
Imaging the Nanoscale Band Structure of Topological Sb
Anjan Soumyanarayanan, Michael M. Yee, Yang He +5
Many promising building blocks of future electronic technology - including non-stoichiometric compounds, strongly correlated oxides, and strained or patterned films - are inhomogen…
Measurement of intrinsic Dirac fermion cooling on the surface of a topological insulator BiSe using time- and angle-resolved photoemission spectroscopy
Y. H. Wang, D. Hsieh, E. J. Sie +5
We perform time- and angle-resolved photoemission spectroscopy of a prototypical topological insulator BiSe to study the ultrafast dynamics of surface and bulk electrons af…
Selective probing of photo-induced charge and spin dynamics in the bulk and surface of a topological insulator
D. Hsieh, F. Mahmood, J. W. McIver +3
Topological insulators possess completely different spin-orbit coupled bulk and surface electronic spectra that are each predicted to exhibit exotic responses to light. Here we rep…
Observation of a warped helical spin-texture in BiSe from circular dichroism angle-resolved photoemission spectroscopy
Y. H. Wang, D. Hsieh, D. Pilon +4
A differential coupling of topological surface states to left- versus right-circularly polarized light is the basis of many opto-spintronics applications of topological insulators.…
