Liquid Crystals in Spherical Confinement
Ordered systems, such as liquid crystals, are dramatically affected by confinement and curvature. One of the main consequences is the presence of topological defects in the ground state of the liquid crystal. For instance, when a nematic liquid crystal is confined to a thin spherical shell, theory predicts a configuration with four defects arranged in a tetrahedral fashion. This prediction hold...
متن کاملExpanding Spherical Shell of Charge
in Gaussian units and in spherical coordinates where a(t) is the radius of the shell, Q is the total surface charge, and H(x, x0) = ∫ x −∞ δ(x ′ − x0) dx′ is the Heaviside step function. However, magnetic charges do not exist, so we cannot have a radial magnetic field of the form (1). That is, the magnetic field is zero, B = 0 everywhere, no matter what is the time dependence a(t) of the radius...
متن کاملScaling regimes in spherical shell rotating convection
Rayleigh-Bénard convection in rotating spherical shells can be considered as a simplified analogue of many astrophysical and geophysical fluid flows. Here, we use threedimensional direct numerical simulations to study this physical process. We construct a dataset of more than 200 numerical models that cover a broad parameter range with Ekman numbers spanning 3 × 10−7 ≤ E ≤ 10−1, Rayleigh number...

متن کاملMultistability in rotating spherical shell convection.
The multiplicity of stable convection patterns in a rotating spherical fluid shell heated from the inner boundary and driven by a central gravity field is presented. These solution branches that arise as rotating waves (RWs) are traced for varying Rayleigh number while their symmetry, stability, and bifurcations are studied. At increased Rayleigh numbers all the RWs undergo transitions to modul...
