Vortex ordering in fully-frustrated superconducting systems with dice lattice
نویسنده
چکیده
The structure and the degeneracy of the ground state of a fully-frustrated XY -model are investigated for the case of a dice lattice geometry. The results are applicable for the description of Josephson junction arrays and thin superconducting wire networks in the external magnetic field providing halfinteger number of flux quanta per plaquette. The mechanisms of disordering of vortex pattern in such systems are briefly discussed. PACS numbers: 74.80.-g, 75.10.Hk, 64.60.Cn Typeset using REVTEX

Vortex correlations in a fully frustrated two-dimensional superconducting network
– We have investigated the vortex state in a superconducting dice network using the Bitter decoration technique at several magnetic frustrations f = φ/φ0=1/2 and 1/3. In contrast to other regular network geometries where the existence of a commensurate state was previouly demonstrated, no ordered state was observed in the dice network at f = 1/2 and the observed vortex-vortex correlation length...
متن کاملFluctuation-induced vortex pattern and its disordering in the fully frustrated XY model on a dice lattice
A highly degenerate family of states, in which the adjacent plaquettes with the same sign of vorticity form clusters of three fproposed in Phys. Rev. B 63, 134503 s2001dg, is proven to really minimize the Hamiltonian of the fully frustrated XY model on a dice lattice. The harmonic fluctuations are demonstrated to be of no consequence for the removal of the accidental degeneracy of these states,...

We carry out an extensive Monte Carlo study of phase transitions in 2D superconducting networks, in an applied magnetic field, for square and honeycomb geometries. We consider both systems with a dilute vortex density 1/q, and dense systems near " full frustration " with vortex density 1/2 − 1/q. The dilute case gives the continuum limit as q → ∞, and serves as a model for a uniform superconduc...
متن کاملThree-Dimensional Crystallization of Vortex Strings in Frustrated Quantum Magnets.
We demonstrate that frustrated exchange interactions can produce exotic 3D crystals of vortex strings near the saturation field (H=H(sat)) of body- and face-centered cubic Mott insulators. The combination of cubic symmetry and frustration leads to a magnon spectrum of the fully polarized spin state (H>H(sat)) with degenerate minima at multiple noncoplanar Q vectors. This spectrum becomes gaples...
متن کاملFrustration phenomena in Josephson junction arrays on a dice lattice
AC magnetoimpedance measurements performed on proximity-effect coupled Josephson junction arrays on a dice lattice reveal unconventional behaviour resulting from the interplay between the frustration f created by the applied magnetic field and the particular geometry of the system. While the inverse magnetoinduc-tance exhibits prominent peaks at f = 1/3 and at f = 1/6 (and weaker structures at ...
