Gauge-invariant projector calculus for quantum state geometry and applications to observables in crystals
Johannes Mitscherling, Alexander Avdoshkin, Joel E. Moore
The importance of simple geometrical invariants, such as the Berry curvature and quantum metric, constructed from the Bloch states of a crystal has become well-established over fou…
Coherent Magneto-Conductance Oscillations in Amorphous Topological Insulator Nanowires
Siddhant Mal, Elizabeth J. Dresselhaus, Joel E. Moore
Recent experiments on amorphous materials have established the existence of surface states similar to those of crystalline three-dimensional topological insulators (TIs). Amorphous…
The multi-state geometry of shift current and polarization
Alexander Avdoshkin, Johannes Mitscherling, Joel E. Moore
The quantum metric and Berry curvature capture essential properties of non-trivial Bloch states and underpin many fascinating phenomena. However, it becomes increasingly evident th…
Dark Metastable Conduction Channels near a Metal-Insulator Transition
T. R. Devidas, Dror Yahav, Jonathan T. Reichanadter +7
Materials that transition between metal and insulator, the two main states that distinguish all solids, are fascinating because they underlie many mysteries at the frontier of soli…
A tale of two localizations: coexistence of flat bands and Anderson localization in a photonics-inspired amorphous system
Elizabeth J. Dresselhaus, Alexander Avdoshkin, Zhetao Jia +3
Emerging experimental platforms use amorphousness, a constrained form of disorder, to tailor meta-material properties. We study localization under this type of disorder in a family…
