Observation of a transition to a localized ultrasonic phase in soft matter
Abstract
Anderson localization is a disorder-driven phenomenon typically considered in the context of low-temperature condensed-matter systems. However, the phenomenon can also be relevant to soft matter and here the authors experimentally demonstrate it is possible to observe Anderson localization of ultrasonic waves in soft matter doped with resonant encapsulated microbubbles.
