DPG Conference Dresden 2026
I am currently presenting my latest research results at the Spring Meeting of the German Physical Society (DPG) in Dresden:
“General Polarization Dependent Dynamic Light Scattering Using the Dynamic Mueller Matrix”
This work extends classical dynamic light scattering to include complete polarization-dependent correlations. While conventional DLS only measures intensity fluctuations, the Dynamic Mueller Matrix enables coherent detection of all 16 possible field correlation functions.
Key Concepts:
- Transition from deterministic to stochastic polarization transfer
- Application of the Azzam procedure to intensity autocorrelation functions
- Experimental realization using rotating quarter-wave plates
- Siegert relation for each Mueller matrix element
Applications:
- Shape fluctuations of soft colloidal particles dispersed in water
- Distinction between structural, concentric, and non-concentric fluctuations
- Ellipsometric light scattering for anisotropic interfaces
- Extended correlation ellipsometry
This method opens new possibilities for investigating complex dynamics in soft material systems that are inaccessible with conventional methods.
