Resonant-Cavity-Induced Phase Locking and Voltage Steps in a Josephson Array
E. Almaas, D. Stroud
We describe a simple dynamical model for an underdamped Josephson junction array coupled to a resonant cavity. From numerical solutions of the model in one dimension, we find that…

Fractional vortices in the XY model with bonds
R. V. Kulkarni, E. Almaas, K. D. Fisher +1
We define a new set of excitations in the XY model which we call ``fractional vortices''. In the frustrated XY model containing bonds, we make the ansatz that the ground state…
