Polar response particles in French as remnants of ellipsis

open access: yesGlossa, 2020
Polar response particles have been at the center of lively debates in the recent and not so recent literature. One of these debates concerns the syntax of these particles, in particular whether they are pure sentential proforms or involve ellipsis.

Heat transport and spin-charge separation in the normal state of high temperature superconductors

open access: yes, 2000
Hill et al. have recently measured both the thermal and charge conductivities in the normal state of a high temperature superconductor. Based on the vanishing of the Wiedemann-Franz ratio in the extrapolated zero temperature limit, they conclude that the
