Polarisation textures of light and matter
Polarisation - while invisible to the eye - has been recognized as an 
important feature of light since the days of Ptolemy. Over the last decades 
we have gained unprecedented control over light, allowing us to generate 
polarisation structures in 2D and 3D, explore its topologies and its 
interaction with matter. In this talk I will present how we generate and 
analyse arbitrary polarization textures and introduce you to some of its 
curious properties, including new insights into knife-edge diffraction, and 
optical skyrmions. I will explain how we can transfer optical polarisation 
textures to polariton structures in atomic gasses. Unlike optical 
polarizations, atomic spin alignments react to external fields and forces, 
promising applications in magnetometry and inertial sensing - and vice versa 
allowing us insights into optical properties that can not be detected 
directly with photodiodes or cameras.Thursday, 15 May 2025, 14:00
