Article Description

We address the problem of a relativistic particle in a periodic asymmetric potential of the ratchet type. As a solid-state realization of such a particle, we consider a single-flux quantum in a long annular Josephson junction embedded in an inhomogeneous magnetic field. A deterministic (nonthermal) regime is theoretically investigated and compared with numerical results. The ratchet velocity of the relativistic fluxon is found qualitatively different from that of a nonrelativistic particle. © 2001 The American Physical Society.
