Superfluid Phase Slippage in (3)He-B Flow through a Narrow Channel

摘要

An investigation of phase slippage in flowing superfluid (3)He is presented, based on the numerical integration of time-dependent Ginzburg-Landau equations. The quantum-dynamical phase-slip processes in (3)He are found to be associated with superfluid-core phase-slip centers, in contrast with the resistive state for superconductors where phase-slip centers have normal cores.
