A Renewal of support is sought for research on proton glasses, in which one will examine the effects of cation and anion substitution and of deuteration. The experiments will be carried out in the temperature range 3K to 450K, at hydrostatic pressures up to 4kbar and at higher pressures using opposed-anvil cells. Field-cooling experiments will be conducted in a search for the onset of non- ergodicity, and non-linear effects will be studied by means of 3rd- order dielectric susceptibility measurements.

寻求对质子玻璃研究的更新支持，其中将检查阳离子和阴离子取代以及氘化的影响。 实验将在 3K 至 450K 的温度范围、高达 4kbar 的静水压力和更高的压力下使用对置砧池进行。 将进行场冷却实验来寻找非遍历性的开始，并将通过三阶介电磁化率测量来研究非线性效应。
