Perturbative second-order optical susceptibility of bulk materials: a symmetry-enforced return to non-orthogonal localized basis sets
Angiolo Huaman, Luis Enrique Rosas-Hernandez, Salvador Barraza-Lopez
The second-order optical susceptibility of semiconductors finds application in metrology, spectroscopy, telecommunications, material characterization,…
Reference lattice, sound, stiffness, and magnetic transitions of Ising monolayers
John M. Davis, Amador Garcia-Fuente, Jaime Ferrer +1
A reference lattice, away from which elastic distortions induced by the spin texturing of 2D magnets take hold, is motivated from a picture of pairwise Biot-Savart interactions amo…
Winding Berry dipole on uniaxially strained graphene/hBN/hBN moiré trilayers
Angiolo Huaman, Salvador Barraza-Lopez
Nonlinear Hall-like currents can be generated by a time-periodic alternating bias on two-dimensional (2D) materials lacking inversion symmetry. To hint that the moiré between grap…
Insulating moiré homobilayers lack a threefold symmetric second harmonic generation
Luis Enrique Rosas-Hernandez, Jose Luis Cabellos, Angiolo Huamán +2
Atoms within moiré bilayers relax in-plane to minimize elastic energy [e.g., Cazeaux et al., J. Elast. 154, 443 (2023)]; such relaxation brings their space group symmetries down t…
