 note = {The nonlinear evolution of the Rayleigh-Taylor instability (RTI) at a density shear layer transverse<br/>to magnetic field in a collisionless plasma is investigated by means of a fully kinetic<br/>Vlasov simulation with two spatial and two velocity dimensions. The primary RTI in the MHD<br/>regime develops symmetrically in a coordinate axis parallel to gravity as seen in the previous<br/>MHD simulations. The primary RTI in the Hall-MHD regime develops asymmetrically in a<br/>coordinate axis parallel to gravity. A compressible flow is formed at the secondary density shear<br/>layer by the Hall effect, which generates a strong scalar pressure gradient of ions. A Hall electric<br/>field due to the diamagnetic current results in the asymmetric flow at the tip of the finger structure.<br/>In the primary RTI with the ion gyro kinetic effect, secondary RTI with a wavelength<br/>shorter than the wavelength of the primary RTI is generated at the saturation stage of the primary<br/>RTI. A seed perturbation for the secondary RTI is excited by another secondary instability<br/>due to the coupling between the electron stress tensor and the Hall electric field. The heat<br/>flux term plays an important role in the time development of the total pressure. On the other<br/>hand, the contribution of the ion stress tensor is small in both the electric current and the total<br/>pressure.},
