Multipolar orbital relaxation of the states
Aurélien Manchon, Xiaobai Ning, Chi Sun +3
Using a nonperturbative approach, the relaxation rate of orbital dipolar and quadrupolar moments is computed analytically for the t2g states. In the presence of short-range impurit…
Real-Space Spectral Approach to Orbital Magnetization
Kevin J. U. Vidarte, Henrique P. Veiga, João M. Viana Parente Lopes +4
We present a real-space spectral method for computing the orbital magnetization of crystals. Starting from the commutator form of the orbital magnetization operator, we formulate a…
Orbital Hall effect from orbital magnetic moments of Bloch states: the role of a new correction term
Tarik P. Cysne, Ivo Souza, Tatiana G. Rappoport
We present a rigorous derivation of the matrix elements of the orbital magnetic moment (OMM) of Bloch states. Our calculations include the Berry connection term in the k-derivative…
Real-space first-principles approach to orbitronic phenomena in metallic multilayers
Ramon Cardias, Hugo U. R. Strand, Anders Bergman +2
We develop a real-space first-principles method based on density functional theory to investigate orbitronic phenomena in complex materials. Using the Real-Space Linear Muffin-Tin…
Extrinsic Orbital Hall Effect and Orbital Relaxation in Mesoscopic Devices
Anderson L. R. Barbosa, Hyun-Woo Lee, Tatiana G. Rappoport
Despite recent advances in orbitronics, the influence of disorder on the orbital Hall effect and orbital relaxation mechanisms remains poorly understood. In this work, we numerical…
Symmetry Analysis of the Non-Hermitian Electro-Optic Effect in Crystals
Sylvain Lannebère, Tatiana G. Rappoport, Tiago A. Morgado +2
Here, we investigate how crystal symmetry tailors the non-Hermitian electro-optic effect arising from the Berry curvature dipole. Specifically, we demonstrate the critical influenc…
