Fractional quantum spin Hall crystals from hidden density-wave order
Matthew Shammami, Sudip Chakravarty
Broken symmetry and topology are distinct descriptions for how matter organizes itself. Here, we propose one gives rise to the other. A mixed singlet-triplet -density wave, whic…

Insulating transport in anisotropic metals: breakdown of Drude transport and the puzzling -axis resistivity of SrRuO and other layered oxides
Sophie Beck, Matthew Shammami, Lorenzo Van Muñoz +3
We reveal a mechanism that may explain the non-metallic out-of-plane resistivity in layered metals. By carefully examining how the Drude-Boltzmann expression for the -axis condu…
