Resumen en inglés

Liquid crystals interacting with light represent a unique class of soft-matter systems that exhibit various generic nonlinear behaviors, including chaotic rotational dynamics. Despite several experimental observations, complex nematic liquid crystal director rotations in presence of spin and orbital angular momentum transfer processes were left unexplained. We present a self-consistent three-dimensional model able to describe the previous experimental observations, accounting for the dependence on the incident beam intensity, polarization, finite size and shape. More generally, our model is able to describe quantitatively the dynamics of, and beyond, the optical Fréedericksz transition under realistic experimental conditions almost three decades after its experimental discovery.< Leer menos
