WebIn summary, our work introduces a powerful tuning parameter for electronic Ising-nematic order: strain that breaks different symmetries than the nematic order. For a representative system, we show that shear strain enhances quantum nematic fluctuations, can be varied continuously without introducing disorder, and preserves time-reversal symmetry. WebThe directions of spatial perturbations were varied to probe for instabilities perpendicular and parallel to the orientation of the spatially uniform (polar and nematic) order parameters. Based on this analysis we identified the type of order exhibited by spatially uniform solutions, as well as their stability against wave-like perturbation for different values of …

Web1 day ago · We present an analysis and numerical study of an optimal control problem for the Landau-de Gennes (LdG) model of nematic liquid crystals (LCs), which is a crucial component in modern technology. They exhibit long range orientational order in their nematic phase, which is represented by a tensor-valued (spatial) order parameter .
