Vortex-enhanced photovoltaic current in disordered topological materials
Pavlo Sukhachov, Penghao Zhu, Ella Banyas +2
In disordered topological materials, real-space crystalline defects interplay with momentum-space wave function singularities to \textit{enhance} the bulk photovoltaic current. Wha…
Reply to: Low-frequency quantum oscillations in LaRhIn: Dirac point or nodal line?
Chunyu Guo, A. Alexandradinata, Carsten Putzke +16
We thank G.P. Mikitik and Yu.V. Sharlai for contributing this note and the cordial exchange about it. First and foremost, we note that the aim of our paper is to report a methodolo…
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…
Temperature dependence of quantum oscillations from non-parabolic dispersions
Chunyu Guo, A. Alexandradinata, Carsten Putzke +16
The phase offset of quantum oscillations is commonly used to experimentally diagnose topologically non-trivial Fermi surfaces. This methodology, however, is inconclusive for spin-o…
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…
A new form of (unexpected) Dirac fermions in the strongly-correlated cerium monopnictides
Nasser Alidoust, A. Alexandradinata, Su-Yang Xu +14
Discovering Dirac fermions with novel properties has become an important front in condensed matter and materials sciences. Here, we report the observation of unusual Dirac fermion…
