Diabolical touching point in the magnetic energy levels of topological nodal-line metals
Chong Wang, Zhongyi Zhang, Chen Fang +1
For three-dimensional metals, Landau levels disperse as a function of the magnetic field and the momentum wavenumber parallel to the field. In this two-dimensional parameter space,…
Quantized surface magnetism and higher-order topology: Application to the Hopf insulator
Penghao Zhu, Taylor L. Hughes, A. Alexandradinata
We identify topological aspects of the subextensive magnetic moment contributed by the surfaces of a three-dimensional crystallite -- assumed to be insulating in the bulk as well a…
Teleportation of Berry curvature on the surface of a Hopf insulator
A. Alexandradinata, Aleksandra Nelson, Alexey A. Soluyanov
The existing paradigm for topological insulators asserts that an energy gap separates conduction and valence bands with opposite topological invariants. Here, we propose that \text…
Crystallographic splitting theorem for band representations and fragile topological photonic crystals
A. Alexandradinata, J. Höller, Chong Wang +2
The fundamental building blocks in band theory are band representations (BRs): bands whose infinitely-numbered Wannier functions are generated (by action of a space group) from a f…
Quantized frequency-domain polarization of driven phases of matter
Ian Mondragon-Shem, Ivar Martin, A. Alexandradinata +1
Periodically driven quantum systems can realize novel phases of matter that do not exist in static settings. We study signatures of these drive-induced phases on the -dimens…
Landau quantization of nearly degenerate bands, and full symmetry classification of avoided Landau-level crossings
Chong Wang, Wenhui Duan, Leonid Glazman +1
Semiclassical quantization rules compactly describe the energy dispersion of Landau levels, and are predictive of quantum oscillations in transport and thermodynamic quantities. Su…
