Intrinsic radial superconducting diode effect
Published on 2026-03-12 by Chuan-Shuai Huang, Weinan Lin and Xiancong Lu @IOP SCIENCE
Abstract: Using Ginzburg–Landau theory, we investigate the angular dependence of the intrinsic superconducting diode effect (SDE) in systems with mixed conventional Rashba and radial Rashba (RR) spin–orbit couplings (SOC), characterized by the so-called Rashba angle . Our results show that the admixture of the tangential and radial spin-textures introduces a pronounced phase shift in the dependence of diode efficiency η on magnetic field angle —a hallmark of the radial SDE arising from RR SOC. Impo[...]
Our summary: This study investigates the intrinsic superconducting diode effect using Ginzburg–Landau theory. It reveals a pronounced phase shift in diode efficiency due to mixed Rashba spin-orbit couplings. Higher-order magnetic field corrections show a distinct non-sinusoidal angular dependence, indicating the potential for optimizing diode devices.

Bulk photovoltaic effects of 2D Dirac systems in a temperature gradient
Published on 2026-02-26 by Yang Gao @IOP SCIENCE
Abstract: The bulk photovoltaic effect (BPVE) is the generation of a DC photocurrent in materials that typically requires broken inversion symmetry and plays a crucial role in nonlinear optics and optoelectronics. Here, we theoretically study the BPVE in inversion-symmetric two-dimensional Dirac systems under a temperature gradient, which breaks the inversion symmetry by creating a nonequilibrium steady state. We demonstrate a Drude-like resonant structure in the low-frequency region arising from the jerk[...]
Our summary: This study investigates the bulk photovoltaic effect in inversion-symmetric 2D Dirac systems under a temperature gradient. It reveals that the injection process dominates the BPVE conductivity and identifies resonant structures in the frequency response. The findings suggest new applications for materials with inversion symmetry in nonlinear optoelectronics.
