The interaction of light beams with helical defects in optical materials generates optical
vortices. Understanding and manipulating the dynamics of helical defects allows for the …

Multistable systems are characterized by exhibiting domain coexistence, where each
domain accounts for the different equilibrium states. In case these systems are described by …

Physical systems can exhibit transitions between states with and without topological
properties. These transitions have been observed in conductors to superconductors, fluids to …

In the standard liquid crystal (LC) geometry, one generally finds a quasi‐parabolic director
profile in the vertical direction, where the directors are aligned with an applied field in the …

Based on the electrically controlled birefringence effect in liquid crystal materials, an
effective method for spatially separating azimuthally and radially polarized beams from non …

We theoretically propose the magneto-optically reorientation-induced image reconstruction
in bulk nematic liquid crystals (NLCs). The underlying signals are reinforced and recovered …

By the application of electromagnetic fields onto an homeotropic nematic liquid crystal cell it
is possible to induce vortices, which are particle-type defects with topological charge. The …

Optical vortex generation has attracted great interest in the scientific community due to its
broad applicability in various technological developments. Several studies on optical vortex …

Multistable systems are characterized by exhibiting domain coexistence, where each
domain accounts for the different equilibrium states. In case these systems are described by …

Understanding and manipulating the dynamics of umbilical defects (vortices) allows for the
creation of versatile sources of optical vortices. Optical vortices have drawn attention for their …
