title: Vortex-lattice phases of superfluid (3)He in rapid rotation.
abstract: Superfluid 3He in the angular velocity of 0.01 Omega(c2) < or = Omega < or = Omega(c2) is studied theoretically, where Omega(c2) is the upper critical field of order (1 - T/T(c)) x 10(7) rad/s. Five different phases have been found in the pressure-Omega plane. Especially, it is shown that the A-phase-core vortex experimentally found in the B phase originates from Schopohl's polar state at Omega(c2) via an A-phase mixed-twist lattice with polar cores and the normal-core lattice of Ohmi, Tsuneto, and Fujita [Prog. Theor. Phys. 70, 647 (1983)].
