Alternative derivation of the Feigel effect and call for its experimental verification

, 2011
A recent theory by Feigel [Phys. Rev. Lett. {\bf 92}, 020404 (2004)] predicts the finite transfer of momentum from the quantum vacuum to a fluid placed in strong perpendicular electric and magnetic fields.

Phonon‐Driven Insights Into Layer Sliding of High‐Voltage Layered Cathode

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Understanding the structural instability of high‐voltage layered cathodes remains a critical challenge in advancing sodium‐ion batteries. This work proposes a breathing‐shear mode coupling model based on the phonon spectrum, which elucidates the layer sliding mechanism in layered cathode materials by using interlayer spacing as the order parameter.

Fluidisation and plastic activity in a model soft-glassy material flowing in micro-channels with rough walls

, 2016
By means of mesoscopic numerical simulations of a model soft-glassy material, we investigate the role of boundary roughness on the flow behaviour of the material, probing the bulk/wall and global/local rheologies.

Shape of the ocean surface and implications for the Earth's interior: GEOS-3 results [PDF]

A new set of 1 deg x 1 deg mean free air anomalies was used to construct a gravimetric geoid by Stokes' formula for the Indian Ocean. Utilizing such 1 deg x 1 deg geoid comparisons were made with GEOS-3 radar altimeter estimates of geoid height.

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...
