Abstract
Superconducting phase transitions are investigated in an aluminum kagomé wire network at different values of uniform frustration with special emphasis on half-filling. While the mean-field phase diagram shows no cusp at half-filling signifying a frustrated ground state, thermal fluctuations appear to restore an ordered state, as seen in the appearance of a cusp in the phase boundaries. Detailed I-V characteristics indicate a unique transition at half-filling, distinct from that observed at irrational or other rational fillings.
