Orbital Kerr effect and terahertz detection via the nonlinear Hall effect
Diego Garcia Ovalle, Armando Pezo, Aurélien Manchon
We investigate the optical response induced by a d.c. current flowing in a nonmagnetic material that lacks inversion symmetry. In this class of materials, the flowing current exper…
Orbital diffusion, polarization and swapping in centrosymmetric metals
Xiaobai Ning, A. Pezo, Kyoung-Whan Kim +3
We propose a general theory of charge, spin, and orbital diffusion based on Keldysh formalism. Our findings indicate that the diffusivity of orbital angular momentum in metals is m…
Electronic and spin transport in Bismuthene with magnetic impurities
Armando Pezo, Felipe Crasto de Lima, Adalberto Fazzio
Topological insulators have remained as candidates for future electronic devices since their first experimental realization in the past decade. The existence of topologically prote…
Orbital Pumping by Magnetization Dynamics in Ferromagnets
Dongwook Go, Kazuya Ando, Armando Pezo +3
We show that dynamics of the magnetization in ferromagnets can pump the orbital angular momentum, which we denote by orbital pumping. This is the reciprocal phenomenon to the orbit…
Spin-orbit torque for field-free switching in C_{3v} crystals
Diego García Ovalle, Armando Pezo, Aurélien Manchon
Spin-orbit torques in noncentrosymmetric polycrystalline magnetic heterostructures are usually described in terms of field-like and damping-like torques. However, materials with a…
Electronic transport properties of MoS nanoribbons embedded on butadiene solvent
Armando Pezo, Matheus P. Lima, Marcio Costa +1
Transition metal dichalcogenides (TMDCs) are promising materials for applications in nanoelectronics and correlated fields, where their metallic edge states play a fundamental role…
Orbital Hall physics in two-dimensional Dirac materials
Armando Pezo, Diego García Ovalle, Aurélien Manchon
Orbitronics has recently emerged as a very active research topic after several proposals aiming to exploit the orbital degree of freedom for charge-free electronics. In this commun…
