I am a french PhD student working with Patrick Oswald in the Matter & Complexity team of the Physics Laboratory at the ENS de Lyon. We are interested in the thermal Lehmann effect, an out-of-equilibrium effect which couples a temperature gradient with the rotation of the internal texture of liquid crystal droplets in equilibrium with the isotropic phase, in condition that this texture is chiral.
My PhD project includes experimental, numerical and theoretical aspects. In particular, I have participated in the design of a Fluorescence Recovery After Photobleaching (FRAP) experimental setup, and used this setup to show that there is no flow in the Lehmann experiment. I also developped a Finite Element code using the Deal.II library to solve the nematoelasticity equations with finite anchoring boundary conditions. This code was useful to compute the texture inside cholesteric and nematic droplets and test the validity of particular theoretical models.
