Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures

Advanced Materials, EarlyView.
An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

Orbital angular momentum dichroism in nanoantennas [PDF]

, 2018
When light interacts with matter, dichroism with respect to the handedness of circularly polarized light is well established. But what happens if the light further possesses an orbital angular momentum?

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Crystal symmetry-dependent Orbital Rashba Edelstein effect in epitaxial CuO thin film

Nature Communications
Orbital angular momentum has recently been demonstrated as a promising approach to manipulate magnetic order in spintronic devices with high efficiency. While the generation of orbital angular momentum is generally attributed to electron orbital hopping ...

Unveiling a truncated optical lattice associated with a triangular aperture using light’s orbital angular momentum [PDF]

, 2010
We show that the orbital angular momentum can be used to unveil lattice properties hidden in diffraction patterns of a simple triangular aperture. Depending on the orbital angular momentum of the incident beam, the far field diffraction pattern reveals a

Ground-state phase diagram of a spin-orbital-angular-momentum coupled Bose-Einstein condensate

, 2019
By inducing a Raman transition using a pair of Gaussian and Laguerre-Gaussian laser beams, we realize a Rb87 condensate whose orbital angular momentum (OAM) and its internal spin states are coupled.
