Role of disorder in the intrinsic orbital hall effect

P Tang, GEW Bauer - Physical Review Letters, 2024 - APS
The orbital Hall effect (OHE) has garnered much attention as a promising approach to
realize highly efficient “orbitronic” devices with a wide range of materials. However, the …

Electric-field-induced orbital angular momentum in metals

KJ Lee, V Cros, HW Lee - nature materials, 2024 - nature.com
Electrons in solids carry orbital angular momentum in diverse non-equilibrium situations.
This orbital current is often overlooked when considering electronic transport. Here we …

Orbital pum** incorporating both orbital angular momentum and position

S Han, HW Ko, JH Oh, HW Lee, KJ Lee, KW Kim - Physical Review Letters, 2025 - APS
We develop a theory of adiabatic orbital pum**, highlighting qualitative differences from
spin pum**. An oscillating magnetic field pumps not only orbital angular momentum …

Intrinsic torque on the orbital angular momentum in an electric field

RB Atencia, DP Arovas, D Culcer - Physical Review B, 2024 - APS
Orbitronics harnesses nonequilibrium densities and flows of electrons' orbital angular
momentum (OAM). Although the OAM must be long lived to be useful in information …

Orbital angular momentum of Bloch electrons: equilibrium formulation, magneto-electric phenomena, and the orbital Hall effect

R Burgos Atencia, A Agarwal, D Culcer - Advances in Physics: X, 2024 - Taylor & Francis
The investigation of orbital angular momentum (OAM) of delocalised Bloch electrons has
advanced our understanding of magnetic, transport, and optical phenomena in crystals …

Dyakonov-Perel-like Orbital and Spin Relaxations in Centrosymmetric Systems

J Sohn, JM Lee, HW Lee - Physical Review Letters, 2024 - APS
The Dyakonov-Perel (DP) mechanism of spin relaxation has long been considered
irrelevant in centrosymmetric systems since it was developed originally for …

Ultrathin films of black phosphorus as suitable platforms for unambiguous observation of the orbital Hall effect

TP Cysne, M Costa, MB Nardelli, RB Muniz… - Physical Review B, 2023 - APS
Phosphorene, a monolayer of black phosphorus, is a two-dimensional material that lacks a
multivalley structure in the Brillouin zone and has negligible spin-orbit coupling. This makes …

Topological orbital Hall effect caused by skyrmions and antiferromagnetic skyrmions

B Göbel, L Schimpf, I Mertig - Communications Physics, 2025 - nature.com
The topological Hall effect is a hallmark of topologically non-trivial magnetic textures such as
magnetic skyrmions. It quantifies the transverse electric current that is generated once an …

Quantum correction to the orbital Hall effect

H Liu, JH Cullen, DP Arovas, D Culcer - Physical Review Letters, 2025 - APS
Evaluations of the orbital Hall effect (OHE) have retained only interband matrix elements of
the position operator. Here, we evaluate the OHE including all matrix elements of the …
