WebSep 30, 2024 · Our results show that chiral structures and related topological defects in Cr 1/3 TaS 2 occur at a remarkably wide variety of length scales: from the nanometer-sized structural chiral pitch (1.2 nm), magnetic helical pitch (15 nm), and CyMS pitch (∼200 nm or larger) to the macroscopic scale (1 to 100 μm) of topological vortex domains (SI ... WebAug 28, 2013 · We employ Monte Carlo simulations in a specialized isothermal-isobaric and in the grand canonical ensemble to study structure formation in chiral liquid crystals as a function of molecular chirality. Our model potential consists of a simple Lennard-Jones potential, where the attractive contribution has been modified to represent the orientation …
