AbstractWe propose an implicit finite-difference method to study the time evolution of the director field of a nematic liquid crystal under the influence of an electric field with weak anchoring at the boundary. The scheme allows us to study the dynamics of transitions between different director equilibrium states under varying electric field and anchoring strength. In particular, we are able to simulate the transition to excited states of odd parity, which have previously been observed in experiments, but so far only analyzed in the static case.

The Mean

We select the asymmetric Gaussian (AG) and the parabolic (P) confinement to describe the along growth direction and perpendicular to growth direction confinement potential (CP) of an electron in a disk-like quantum dot (QD), respectively. Using the Pekar-type variational (PTV) method, we investigate the eigenenergies of the ground and first-excited states (GFES) of the polaron in the QD, changing the QD dimensions. We study the hydrogen-like impurity (HLI) and the polarization effect. Our numerical results show the influence of the QD dimensions on the mean number of phonons, energies, transition frequency and probability. The Coulomb potential of hydrogen-like impurity and the polarization effect of the medium cannot be ignored. We find that the electric field is an indispensable condition for the induced polaron transition. The weak electric field has a strong regulatory function on the transition. AG confinement is more drastic than P confinement in modulating polaron transition properties. This work confirms that the choice of a CP is crucial for the study of polaron transition in nanostructures. This quantum system can be employed as a two-level quantum qubit.
