Observation of Majorana Fermions in Ferromagnetic Atomic Chains on a Superconductor
Stevan Nadj-Perge, Ilya K. Drozdov, Jian Li +6
Majorana fermions are predicted to localize at the edge of a topological superconductor, a state of matter that can form when a ferromagnetic system is placed in proximity to a con…
One-dimensional Topological Edge States of Bismuth Bilayers
Ilya K. Drozdov, A. Alexandradinata, Sangjun Jeon +5
The hallmark of a time-reversal symmetry protected topologically insulating state of matter in two-dimensions (2D) is the existence of chiral edge modes propagating along the perim…
Landau Quantization and Quasiparticle Interference in the Three-Dimensional Dirac Semimetal Cd3As2
Sangjun Jeon, Brian B. Zhou, Andras Gyenis +7
Condensed matter systems provide a rich setting to realize Dirac and Majorana fermionic excitations and the possibility to manipulate them in materials for potential applications.…
