Spin and orbital-to-charge conversion in noncentrosymmetric materials: Hall versus Rashba-Edelstein effects
Diego Garcia Ovalle, Aurelien Manchon
We investigate spin- and orbital-to-charge conversion phenomena in nonmagnetic materials with broken inversion symmetry, treating the contributions from the Hall effect and the Ras…
Moiré amplification of highly tunable shift current response in twisted trilayer graphene
Yuncheng Mao, Claudio Attaccalite, Diego García Ovalle
In this work we analyze the shift current conductivity in helical twisted trilayer graphene. Without loss of generality, we show that the density of states and the twist angle set…
On the existence of nematic-superconducting states in the Ginzburg-Landau regime
Mariano De Leo, Juan Pablo Borgna, Diego García Ovalle
In this article, we investigate the existence of nematic-superconducting states in the Ginzburg-Landau regime, both analytically and numerically. From the configurations considered…
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…
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…
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…
Influence of the surface states on the nonlinear Hall effect in Weyl semimetals
Diego García Ovalle, Armando Pezo, Aurélien Manchon
We investigate the influence of surface states on the nonlinear Hall response of non-centrosymmetric time-reversal invariant Weyl semimetals. To do so, we perform a tomography of t…
Orbital Hall effect in crystals: inter-atomic versus intra-atomic contributions
Armando Pezo, Diego Garcia Ovalle, Aurelien Manchon
The orbital Hall effect (OHE) designates the generation of a charge-neutral flow of orbital angular momentum transverse to an initial charge current. Recent theoretical investigati…
Interaction Between Two Single Superconducting Vortices Inside A Superconducting Hollow Cylindrical domain
Diego García Ovalle, Enrique Muñoz, Rafael D. Benguria
Inspired by the seminal, ground-breaking work of Abrikosov in 1957, we developed a new approximation to the interaction between two widely separated superconducting vortices. In co…
