Intrinsic Orbital Hall Effect in Degenerate Spin-3/2 Systems driven by the quantum metric
Rhonald Burgos Atencia
We show that in rotationally invariant spin- systems the orbital Hall effect originates from interband matrix elements of the orbital magnetic moment. The resulting Hall respo…
Quantum metric quadrupoles in elemental bismuth thin films
Rhonald Burgos Atencia, Pavlo Makushko, Gabriele Naselli +11
The nonlinear transport properties of solids are deeply rooted in the quantum geometry of their electronic wavefunctions, which is encoded in the quantum geometric tensor. Its real…
Skew scattering induced contribution to orbital Hall response
Dayana Joy, Vivek Pandey, Rhonald Burgos Atencia +1
Our study provides the disorder-induced contribution to the orbital Hall conductivity in three-dimensional Weyl semimetals with broken time-reversal symmetry. Using the quantum kin…
Quantum geometry and linear orbital response in arbitrary representation
Rhonald Burgos Atencia
We develop a unified framework to compute band-geometric quantities in multiband systems whose low-energy Hamiltonians realize arbitrary representations. Exploiting the pre…
Zeeman-activated Berry curvature magnetotransport from the bulk of non-magnetic metals with inversion symmetry
Rhonald Burgos Atencia, Antonio Vecchione, Denys Makarov +1
The Berry curvature (BC), a quantity encoding the geometry of electronic wavefunctions, governs various electronic transport effects in quantum materials. In magnetic systems, the…
Room-Temperature Disorder-Driven Nonlinear Transport in Topological Materials
Rhonald Burgos Atencia, Shanshan Liu, Kian Ping Loh +1
Recent experiments have reported nonlinear signals in topological materials up to room temperature. Here we show that this response stems from extrinsic spin-orbit contributions to…
Intrinsic torque on the orbital angular momentum in an electric field
Rhonald Burgos Atencia, Daniel P. Arovas, Dimitrie Culcer
Orbitronics harnesses non-equilibrium densities and flows of electrons orbital angular momentum (OAM). Although the OAM must be long lived to be useful in information processing, t…
Disorder in the non-linear anomalous Hall effect of -symmetric Dirac fermions
Rhonald Burgos Atencia, Di Xiao, Dimitrie Culcer
The study of the non-linear anomalous Hall effect (NLAHE) in -symmetric systems has focussed on intrinsic mechanisms. Here we show that disorder contributes…
Coherent backscattering in the topological Hall effect
Hong Liu, Rhonald Burgos Atencia, Nikhil Medhekar +1
The mutual interplay between electron transport and magnetism has attracted considerable attention in recent years, primarily motivated by strategies to manipulate magnetic degrees…
Intrinsic nonlinear conductivities induced by the quantum metric
Kamal Das, Shibalik Lahiri, Rhonald Burgos Atencia +2
The second-order nonlinear current originates from three physical mechanisms: extrinsic nonlinear Drude and Berry curvature dipole and intrinsic Berry connection polarizability. He…
Spin transfer torques due to the bulk states of topological insulators
James H. Cullen, Rhonald Burgos Atencia, Dimitrie Culcer
Spin torques at topological insulator (TI)/ferromagnet interfaces have received considerable attention in recent years with a view towards achieving full electrical manipulation of…
Semiclassical equations of motion for disordered conductors: extrinsic interband velocity, corrected collision integral and spin-orbit torques
Rhonald Burgos Atencia, Qian Niu, Dimitrie Culcer
The semiclassical equations of motion are widely used to describe carrier transport in conducting materials. Nevertheless, the substantial challenge of incorporating disorder syste…
