Ferroelectric quantum Hall phase revealed by visualizing Landau level wavefunction interferenc
Quantum materials are a rich platform in which to explore novel phenomena that emerge due to interactions between electrons, giving rise to new phases of matter that cannot be explained by the properties of isolated, non-interacting electrons. Just like electrons have a spin degree of freedom, they can also be associated with... full story: Nature Physics 14 (May 2018) |

Imaging Anyons with Scanning Tunneling Microscopy
We combine analytical calculations with numerical simulations to demonstrate that an STM could visualize the structure of interacting electronic states of FQH states. Spectroscopy mapping with the STM near individual impurity defects can be used to image fractional statistics in FQH states, identifying unique signatures in such... full story: Physical Review X 8 (March 2018) |

High-resolution studies of the Majorana atomic chain platform
Recent experiments have shown that chains of Fe atoms on Pb generically have the required electronic characteristics to form a 1D topological superconductor and have revealed spatially resolved signatures of localized Majorana Fermion quasiparticle (MQP) end modes. With significantly better energy resolution...full story: Nature Physics 13 (Nov. 2016) |

One-dimensional topological edge states of bismuth bilayers Bismuth bilayers have been among the first systems theoretically predicted to be a two-dimensional topological insulator. We have been able to study the topological edge modes of bismuth bilayer system by carrying out scanning tunneling spectroscopy measurements on bulk bismuth samples. By... full story: Nature Physics 10 (Aug. 2014) |
