Abstract
Information is created when a system is changed. This information can be detected by waves, in our case by electromagnetic waves, created and measured far from the creation point. I will shortly introduce Fisher information and the generalized Wigner Smith operator and then show how the information transport can be visualized using the Fisher information flow, similar to the Poynting vector showing the energy flow. The main focus of the talk will be on the experimental realization in a microwave waveguide supporting 4 transporting modes.
Short Biography
Research interests:
Quantum/Wave Chaos, Waves in complex systems, Anderson localization, correlated disorder, theory and experiments in the framework of random matrix and the effective Hamiltonian, Quantum graphs/microwave networks, tight binding experiments, topological systems, non-linear scattering.
