Discrete Breathers in Josephson Ladders
E. Trias, J. J. Mazo, A. Brinkman +1
We present a study of nonlinear localized excitations called discrete breathers in a superconducting array. These localized solutions were recently observed in Josephson-junction l…
Depinning of kinks in a Josephson-junction ratchet array
E. Trias, J. J. Mazo, F. Falo +1
We have measured the depinning of trapped kinks in a ratchet potential using a fabricated circular array of Josephson junctions. Our ratchet system consists of a parallel array of…
Discrete breathers in dc biased Josephson-junction arrays
J. J. Mazo, E. Trias, T. P. Orlando
We propose a method to excite and detect a rotor localized mode (rotobreather) in a Josephson-junction array biased by dc currents. In our numerical studies of the dynamics we have…
Discrete breathers in nonlinear lattices: Experimental detection in a Josephson array
E. Trias, J. J. Mazo, T. P. Orlando
We present an experimental study of discrete breathers in an underdamped Josephson-junction array. Breathers exist under a range of dc current biases and temperatures, and are dete…
Discreteness-induced resonances and AC voltage amplitudes in long one-dimensional Josephson junction arrays
A. E. Duwel, S. Watanabe, E. Trias +3
New resonance steps are found in the experimental current-voltage characteristics of long, discrete, one-dimensional Josephson junction arrays with open boundaries and in an extern…
Resonances of dynamical checkerboard states in Josephson arrays with self-inductance
M. Barahona, E. Trias, T. P. Orlando +4
We study the dynamics of fully frustrated, underdamped Josephson arrays. Experiments reveal remarkable similarities among the dc current-voltage characteristics of several kinds of…
