【 摘 要 】

By studying a nonlinear susceptibility on supercooled glycerol, we show that applying a static field E-st increases the glass transition temperature T-g by an amount quadratic in E-st. This has important consequences: (i) it reinforces the relation between the two paths put forward in the last years to unveil the dynamical correlation volume close to T-g; (ii) it clarifies the interpretation of nonlinear measurements; (iii) it yields a new control parameter of the glass transition, which paves the way for experiments deepening our understanding of glasses.
