Confinement effects in bulk supercooled liquids

Research output: Contribution to journalArticlepeer-review

11 Scopus citations


Supercooled liquids are known to display heterogeneous dynamics, with slow and fast relaxation modes being independent and even spatially separated in dynamically distinct domains. In such a situation, it is imaginable that the very fast modes are surrounded by material that is practically frozen on the relaxation time scale of that fast mode. Here, we show experimental evidence of such a confinement effect. For the fastest few percent of all modes, equilibration appears to be linked to a common process (e. g. macroscopic softening), while the remaining majority equilibrate on the time scale of their individual time constant, as expected for heterogeneous dynamics.
