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 …

Extrinsic Orbital Hall Effect: Interplay Between Diffusive and Intrinsic Transport

A Veneri, TG Rappoport, A Ferreira - arxiv preprint arxiv:2408.04492, 2024 - arxiv.org
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 still …

Transport of orbital currents in systems with strong intervalley coupling: The case of Kekulé distorted graphene

TP Cysne, RB Muniz, TG Rappoport - SciPost Physics Core, 2024 - scipost.org
We show that orbital currents can describe the transport of orbital magnetic moments of
Bloch states in models where the formalism based on valley current is not applicable. As a …
