Optical investigation of low-temperature electric-field-induced relaxations in amorphous solids
Article Abstract:
A study was conducted to analyze the electrical characteristics of a two-level system in two-polymer glasses. Two types of polymers were examined, namely polymethylmethacrylate and polystyrene. The time evolution of a spectral hole was also analized in an electric field cycling experiment. Results indicated that the time evolution of the field-induced spectral diffusion correlated qualitatively with model predictions.

Revised Ehrenfest relations for the glass transition
Article Abstract:
Ehrenfest relations for a second-order phase transition have included glass transitions with low temperature that is out of equilibrium. Glass transition pressure over a wide range of temperature has been predicted by the revised relations.

Correlation between dispersivity of charge transport and holographic response time in an organic photorefractive glass
Article Abstract:
A new organic photorefractive material is presented which shows excellent photoconductive and nonlinear optical properties. The choice of a suitable plasticizer is shown to be important for dispersing charge transport.
