vortices, as quantum objects, can interfere constructively or destructively after following two different paths enclosing a

We develop fast algorithms for the numerical study of two-dimensional triangular Josephson junction arrays. The Dirac bra-ket for-charge placed at the center of the hexagon [21]. The ground malism is introduced in the context of such arrays. We note that state configuration of triangular arrays under the applicatriangular arrays can have both hexagonal and rectangular periodiction of an external magnetic field has unique features of ity and develop algorithms for each. Boundaries are next introduced its own. For example, domain wall superlattices [22] occur and fast algorithms for finite arrays are developed. ᮊ 1997 Acaat characteristic values of f, the quantum of magnetic flux demic Press threading a plaquette, and there is an accidental degeneracy of the ground state [23] for f ϭ and .
