DY 42: Focus: Many-Body Quantum Chaos

Donnerstag, 4. April 2019, 09:30–13:00, H20

The inter-relation between the complex time evolution of interacting many-body quantum systems and the corresponding often classically chaotic, high-dimensional dynamics of their classical counterparts has received increasing interest in various fields in the recent past, ranging from quantum statistical mechanics and quantum chaos via atomic and condensed quantum matter to high energy physics. This Focus Session will comprise recent developments and different perspectives in this emerging research area.
