The quantum world blatantly defies intuitions that people have developed whereas living among relatively massive things, like cars, pennies, and dirt motes. In the quantum world, small particles can maintain a special connection over any distance, pass through barriers, and concurrently journey down multiple paths.
The less broadly recognized quantum behavior is dynamical localization, a phenomenon in which a quantum object stays at a similar temperature despite a gradual supply of energy—bucking the belief that a cold object will always steal warmth from a warmer object.
This assumption is one of the cornerstones of thermodynamics—the study of how heat moves around. The fact that dynamical localization defies this principle signifies that something uncommon is happening within the quantum world—and that dynamical localization may be a wonderful probe of the place the quantum domain ends and traditional physics begins.
Understanding how quantum systems maintain or fail to keep up, quantum behavior is crucial not only to the understanding of the universe but also to the sensible development of quantum technologies.
Until now, dynamical localization has been noticed for single quantum objects, which has stopped it from adding to attempts to pin down where the changeover happens.
To explore this issue, Rylands, along with JQI Fellow Victor Galitski and other colleagues, reviewed mathematical models to see if dynamical localization can nonetheless arise when many quantum particles interact.
