Entropy-driven enhanced self-diffusion in confined reentrant supernematics
Entropy-driven enhanced self-diffusion confined reentrant supernematics
2010/11/17
We present a molecular dynamics study of reentrant nematic phases using the Gay-Berne-Kihara
model of a liquid crystal in nanoconfinement. At densities above those characteristic of smectic A phases,...
Suppression of nuclear spin diffusion at a GaAs/AlGaAs interface measured with a single quantum dot nano-probe
Suppression of nuclear spin GaAs/AlGaAs interface quantum dot nano-probe
2010/4/8
Nuclear spin polarization dynamics are measured in optically pumped individual GaAs/AlGaAs interface quantum dots by detecting the time-dependence of the Overhauser shift in photoluminescence (PL) spe...
