Observation of single-quantum vortex splitting in the BaKFeAs superconductor
Q. Z. Zhou, B. R. Chen, B. K. Xiang +12
Since their theoretical discovery more than a half-century ago, vortices observed in bulk superconductors have carried a quantized value of magnetic flux determined only by fundame…
Direct observation of quantum anomalous vortex in Fe(Se,Te)
Y. S. Lin, S. Y. Wang, X. Zhang +15
Vortices are topological defects of type-II superconductors in an external magnetic field. In a similar fashion to a quantum anomalous Hall insulator, quantum anomalous vortex (QAV…
Improving spatial resolution of scanning SQUID microscopy with an on-chip design
Y. P. Pan, J. J. Zhu, Y. Feng +7
Scanning superconducting quantum interference device microscopy (sSQUID) is currently one of the most effective methods for direct and sensitive magnetic flux imaging on the mesosc…
Observation of chiral currents at the magnetic domain boundary of a topological insulator
Y. H. Wang, J. R. Kirtley, F. Katmis +3
A magnetic domain boundary on the surface of a three-dimensional topological insulator is predicted to host a chiral edge state, but direct demonstration is challenging. Here, we u…
Driven Electronic States at the Surface of a Topological Insulator
Benjamin M. Fregoso, Y. H. Wang, N. Gedik +1
Motivated by recent photoemission experiments on the surface of topological insulators we compute the spectrum of driven topological surface excitations in the presence of an exter…
