A silicon-on-insulator quantum wire
TL;DR: In this article, the drain current characteristics, when measured as a function of gate voltage at low temperature, exhibit a series of oscillations, which is characteristic of current transport in one-dimensional systems (quantum wires).

Thermopower of Composite Fermions
TL;DR: The magnitudes of the thermopower maxima between the fractional quantum Hall states yield an estimate for the CF Landau-level broadening Gamma(CF) which agrees well with Gamma( CF) deduced from the analysis of the excitation energy gaps for the fractionAL liquid states.

E. Grivei,M. Cassart,Jp. Issi,L. Langer,Bernard Nysten,Jean-Pierre Michenaud,Claude Fabre,André Rassat +7 more
TL;DR: Measurements on the temperature dependence of the specific heat of pure C60 in the range 4 < T < 300 K are reported, and a large hysteresis is observed between 165 and 270 K.

Transport and Magnetic-properties of U(2)m(3)si(5) Silicides (m=co,Rh,Ru)
TL;DR: In this article, the authors report and discuss experimental data on the electrical resistivity p, thermoelectric power S, thermal conductivity kappa, specific heat C and magnetic susceptibility chi of polycrystalline U(2)M(3)Si(5) silicides.

Thermal anomalies and the insulator–metal (I–M) transition in Mn3+/Mn4+ perovskites
Jiri Hejtmanek,Z. Jirák,S. Krupička,C. Martin,Cédric Simon,A. Maignan,B. Raveau,E. Grivei,Jp. Issi +8 more
TL;DR: In this paper, a comparative study of two ferromagnets (Pr0.7Sr0.1Ca0.2MnO3 and Pr0.85K0.15MnNO3) is performed, showing that the properties of perovskite manganites are critically influenced by a strong phonon-electron coupling arising from a Jahn-Teller splitting of e(g) orbitals of the Mn3+ ion and the local lattice effects due to size mismatch of the large cations.
