Abstract

"Dissipation encodes interaction of a quantum system with the environment and regulates the. activation regimes of a Brownian particle. We have engineered grain boundary biepitaxial YBaCuO. junctions to drive a direct transition from quantum activated running state to phase diffusion regime.. The cross-over to the quantum regime is tuned by the magnetic field and dissipation is encoded in. a fully consistent set of junction parameters. To unravel phase dynamics in moderately damped. systems is of general interest for advances in the comprehension of retrapping phenomena and in. view of quantum hybrid technology."
