This paper provides the first study of a new dynamical instability in superfluids. This instability is similar to the two-stream instability known to operate in plasmas. It is analogous to the Kelvin-Helmholtz instability, but has the distinguishing feature that the two fluids are interpenetrating. The instability sets in once the relative flow between the two components of the system reaches a critical level. Our analysis is based on the two-fluid equations that have been used to model the…

Dynamics of vortices and interfaces in superfluid 3He

Rapid new developments have occurred in superfluid hydrodynamics since the discovery of a host of unusual phenomena which arise from the diverse structure and dynamics of quantized vortices in 3He

Are pulsar glitches triggered by a superfluid two-stream instability?

A superfluid analog of the two-stream instability that is well known in plasma physics is described and arguments that this instability is likely to be relevant for neutron stars are provided.

Effect of entrainment on stress and pulsar glitches in stratified neutron star crust

The buildup of the stress whose relaxation is presumed to account for pulsar frequency glitches can be attributed to various mechanisms, of which the most efficient involve differential rotation of

Shear flow and Kelvin-Helmholtz instability in superfluids.

The first realization of instabilities in the shear flow between two superfluids is examined and the measured properties of the instability are consistent with the classic Kelvin-Helmholtz theory when modified for two-fluid hydrodynamics.

Negative Energy Modes and Gravitational Instability of Interpenetrating Fluids

ABSTRACT: We study the longitudinal instabilities of two interpenetrating fluids interacting only through gravity. When one of the constituents is of relatively low density, it is possible to have a
