Symmetry-Based Classification of Chern Phases in Honeycomb Photonic Crystals
Rodrigo P. Câmara, Tatiana G. Rappoport, Mário G. Silveirinha
In this work, we develop a symmetry-based classification of Chern phases in honeycomb photonic crystals, considering arbitrary nonreciprocal couplings compatible with energy conser…
Extrinsic Orbital Hall Effect: Orbital Skew Scattering and Crossover Between Diffusive and Intrinsic Orbital Transport
Alessandro Veneri, Tatiana G. Rappoport, Aires Ferreira
Despite the recent success of identifying experimental signatures of the orbital Hall effect (OHE), the research on the microscopic mechanisms behind this unique phenomenon is stil…
Transport of orbital currents in systems with strong intervalley coupling: the case of Kekulé distorted graphene
Tarik P. Cysne, R. B. Muniz, Tatiana G. Rappoport
We show that orbital currents can describe the transport of orbital magnetic moments of Bloch states in models where the formalism based on valley current is not applicable. As a c…
Controlling the orbital Hall effect in gapped bilayer graphene in the terahertz regime
Tarik P. Cysne, W. J. M. Kort-Kamp, Tatiana G. Rappoport
We study the orbital Hall effect (OHE) in the AC regime using bilayer graphene (BLG) as a prototypical material platform. While the unbiased BLG has gapless electronic spectra, app…
Non-Hermitian Linear Electrooptic Effect in 3D materials
Tiago A. Morgado, Tatiana G. Rappoport, Stepan S. Tsirkin +3
Here, we present an in-depth theoretical analysis of the linear electrooptic effect in low-symmetry three-dimensional (3D) conductive materials with large Berry curvature dipoles.…
