Staggered orbital magnetization from itinerant electrons: orbital antiferro- and ferrimagnetic phases
Lucas L. Lage, Kevin J. U. Vidarte, Tarik P. Cysne +3
The authors demonstrate that itinerant electrons on a honeycomb lattice can generate orbital magnetic orders—including ferromagnetic, antiferromagnetic, and ferrimagnetic phases—by…
Real-space topology and charge order in the Haldane-Holstein Model
Sebastião dos Anjos Sousa-Júnior, Julián Faúndez, Tarik P. Cysne +2
We study the half-filled Haldane-Holstein model, where a paradigmatic Chern insulator is coupled to fully dynamical phonons, and provide an unbiased characterization of how retarde…
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…
Orbital magnetization in Sierpinski fractals
L. L. Lage, Tarik. P. Cysne, A. Latgé
Orbital magnetization (OM) in Sierpinski carpet (SC) and triangle (ST) fractal is theoretically investigated by using Haldane model as a prototypical example. The OM calculation is…
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…
Orbitronics in Two-dimensional Materials
Tarik P. Cysne, Luis M. Canonico, Marcio Costa +2
Orbitronics explores the control and manipulation of electronic orbital angular momentum in solid-state systems, opening new pathways for information processing and storage. One si…
