Opto-twistronic Hall effect in a three-dimensional spiral lattice
Zhurun Ji, Yuzhou Zhao, Yicong Chen +7
Studies of moire systems have elucidated the exquisite effect of quantum geometry on the electronic bands and their properties, leading to the discovery of new correlated phases. H…
Protected Fermionic Zero Modes in Periodic Gauge Fields
Vo Tien Phong, Eugene J. Mele
It is well-known that macroscopically-normalizable zero-energy wavefunctions of spin- particles in a two-dimensional inhomogeneous magnetic field are spin-polarized an…
Quantum Geometric Oscillations in Two-Dimensional Flat-Band Solids
Vo Tien Phong, E. J. Mele
Two-dimensional van der Waals heterostructures can be engineered into artificial superlattices that host flat bands with significant Berry curvature and provide a favorable environ…
Boundary Modes from Periodic Magnetic and Pseudomagnetic Fields in Graphene
Vo Tien Phong, E. J. Mele
Single-layer graphenes subject to periodic lateral strains are artificial crystals that can support boundary spectra with an intrinsic polarity. These are analyzed by comparing the…
Optically-Controlled Orbitronics on a Triangular Lattice
Vo Tien Phong, Zachariah Addison, Seongjin Ahn +3
The propagation of electrons in an orbital multiplet dispersing on a lattice can support anomalous transport phenomena deriving from an orbitally-induced Berry curvature. In striki…
Electrodynamics on Fermi Cyclides in Nodal Line Semimetals
Seongjin Ahn, E. J. Mele, Hongki Min
We study the frequency-dependent conductivity of nodal line semimetals (NLSMs), focusing on the effects of carrier density and energy dispersion on the nodal line. We find that the…
