How chaos theory mediates between quantum theory and thermodynamics

Posted by in categories: computing, particle physics, quantum physics

A single particle has no temperature. It has a certain energy or a certain speed—but it is not possible to translate that into a temperature. Only when dealing with random velocity distributions of many particles does a well-defined temperature emerge.

How can the laws of thermodynamics arise from the laws of ? This is a topic that has attracted growing attention in recent years. At TU Wien (Vienna), this question has now been pursued with , which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.
