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…

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…

Reconciling Kubo and Keldysh Approaches to Fermi-Sea-Dependent Nonequilibrium Observables: Application to Spin Hall Current and Spin-Orbit Torque in Spintronics
Simao M. Joao, Marko D. Petrovic, J. M. Viana Parente Lopes +2
Quantum transport studies of spin-dependent phenomena in solids commonly employ the Kubo or Keldysh formulas for the nonequilibrium density operator in the steady-state linear-resp…
