Models for polarization drag-mechanical analog of the Faraday effect-are extended to include inertial corrections to the dielectrics properties of the rotating medium in its rest frame. Instead of the Coriolis-Faraday term originally proposed by Baranova and Zel'dovich [Proc. R. Soc. London A: Math. Phys. Sci. 368, 591 (1979)10.1098/rspa.1979.0148], inertia corrections due to the fictitious Coriolis and centrifugal forces are here derived by considering the effect of rotation on both the Lorentz and plasma dielectric models. These modified rest-frame properties are subsequently used to deduce laboratory properties. Although elegant and insightful, it is shown that the Coriolis-Faraday correction inferred from Larmor's theorem is limited in that it can only capture inertial corrections to polarization drag when the equivalent Faraday rotation is defined at the wave frequency of interest. This is notably not the case for low-frequency polarization drag in a rotating magnetized plasma, although it is verified here using the more general phenomenological models that the impact of fictitious forces is, in general, negligible in these conditions.

Spin Drag Mechanism of Giant Thermal Magnetoresistance.

Phys Rev Lett

We study hydrodynamic thermal transport in high-mobility two-dimensional electron systems placed in an in-plane magnetic field and identify a new mechanism of thermal magnetotransport. This mechanism is caused by drag between the electron populations with opposite spin polarization, which arises in the presence of a hydrodynamic flow of heat. In high mobility systems, spin drag results in strong thermal magnetoresistance, which becomes of the order of 100% at relatively small spin polarization of the electron liquid.

Simultaneous observations of and in Jupiter's northern infrared aurora were conducted on 02 June 2017 using Keck-NIRSPEC to produce polar projection maps of radiance, rotational temperature, column density, and radiance. The temperature variations within the auroral region are K, generally consistent with previous studies, albeit with some structural differences. Known auroral heating sources including particle precipitation, Joule heating, and ion drag have been examined by studying the correlations between each derived quantity, yet no single dominant mechanism can be identified as the main driver for the energetics in Jupiter's northern auroral region.

Investigation of Interface-Induced Helicity-Dependent Photocurrent and High- Ferromagnetism in Wafer-Scale 2D Ferromagnetic FeGeTe/BiTe Heterostructures.

Article Synopsis
  • - The study investigates the helicity-dependent photocurrent (HDPC) in FeGeTe/BiTe heterostructures grown on sapphire substrates, revealing that the photocurrent is primarily driven by the circular photogalvanic effect (CPGE) due to the interface coupling of the materials.
  • - As tensile strain is applied, the CPGE current decreases because the strain reduces the interface-induced spin-orbit coupling; however, the 5 nm FeGeTe/BiTe sample can effectively detect circularly polarized light under the right conditions.
  • - The findings also indicate that the behavior of CPGE depends differently on FeGeTe film thickness compared to Curie temperature, suggesting that strong exchange interactions at the interface may enhance fer

Article Synopsis
  • - The study explores how different molecular structures of multialkylated aromatic amides (MAAs), used as drag reducing agents (DRAs) in natural gas pipelines, impact energy efficiency and corrosion inhibition.
  • - Researchers synthesized MAAs with varying numbers of amide groups and dodecane chains, finding that the molecular structure significantly influences the agents' interfacial activity and film-forming properties on carbon steel surfaces.
  • - Results showed that MAAs with more amide groups and dodecane chains led to thicker and smoother films, enhancing corrosion inhibition and drag reduction rates—specifically, MAA-3 exhibited the highest performance among the synthesized surfactants.

Supramolecular assembly strategy of modified starch chains for achieving recyclable emulsion biocatalysis within a narrow pH range.

Stimuli-responsive Pickering emulsions are promising in biocatalysis for their ease of product separation and emulsifier recovery. However, pH responsiveness, though simple and cost-effective, faces challenges in precise control and narrow transition ranges, limiting its use in enzymatic catalysis. Herein we introduced amorphous octenyl succinic anhydride-modified debranched starch chains (Am-OSA-St) to control emulsion properties within a pH range suitable for enzymatic catalysis.
