Symmetry-isolated magnetoelectric electro-optic effects in noncentrosymmetric metals
C. O. Ascencio, D. J. P. de Sousa, Seungjun Lee +1
We classify the symmetry-constrained forms of the Berry curvature dipole , gyrotropic magnetic tensor , and magnetoelectric electro-optic (EO) tensor $\math…
Metallic electro-optic effects in topological chiral crystals
C. O. Ascencio, D. J. P. de Sousa, Tony Low
Topological chiral crystals have emerged as a fertile material platform for investigating optical phenomena derived from the distinctive Fermi surface Berry curvature and orbital m…
Optical Gain Through Metallic Electro-Optical Effects
N. Roldan-Levchenko, D. J. P. de Sousa, C. O. Ascencio +3
Optical gain is a critical process in today's semiconductor technology and it is most often achieved via stimulated emission. In this theoretical study, we find a resonant TE mode…
Metallic Electro-Optic Effect in Twisted Double-Bilayer Graphene
D. J. P. de Sousa, N. Roldan-Levchenko, C. O. Ascencio +3
Recent theoretical advances have highlighted the role of Bloch state intrinsic properties in enabling unconventional electro-optic (EO) phenomena in bulk metals, offering novel str…
