We investigate the effect of curvature of the tip and the convexity of an electrode on the localization of suspended particles under the combined effect of dielectrophoresis and AC electroosmosis through simulations using COMSOL Multiphysics. A systematic analysis of the parameters defining the convexity of the electrode-the radius of the tip and the apex angle shows that suspended particles can be trapped closely to the electrode edges for comparatively larger tip radii and apex angles. This in turn should favour the trapping of polarizable molecules between the electrodes only if the fluid velocities at the vortices are not very strong.

Using the theoretical formalism of R Liao et al. 9 and Y Zhang et al. 10 , we have theoretically studied spin-orbit coupled fermionic condensate. We have evaluated various parameters as a function of SOC parameter. The evaluated parameters are tricrital temoeratre, tricritical magnetic field, tricritical polarization and two types of critical temperature TCO and TCg all as a function of SOC parameter, Our theoretically obtained results show that all parameter increase and decrease with SOC parameter. These results indicate that there is a competition between SOC and population imbalance due to which these new features have been observed. We hope that the current work will add new excitements in the field of cold atom physics involving artificial gauge field and spin orbit coupling.
