Lifshitz Transition in the Double-Core Vortex in ^{3}He-B.

چکیده
We study the spectrum of fermion states localized within the vortex core of a weak-coupling p-wave superfluid. The low energy spectrum consists of two anomalous branches that generate a large density of states at the locations of the half cores of the vortex. Fermi liquid interactions significantly stretch the vortex structure, which leads to a Lifshitz transition in the effective Fermi surface of the vortex core fermions. We apply the results to the rotational dynamics of vortices in superfluid ^{3}He-B and find an explanation for the observed slow mode.

The superfluid transition of He-He mixture films adsorbed on alumina powder is studied, with a He superfluid coverage near one layer. With up to 1.3 layers of He added, the transition becomes strongly broadened, indicating a linear increase in the vortex core size for He coverages below one layer. Annealing of the sample mixture at 4.2 K is found to be critically important in ensuring a homogen...
متن کاملMeasurement of Turbulence in Superfluid 3 He - B
The experimental investigation of superfluid turbulence in 3 He-B is generally not possible with the techniques which have been developed for 4 He-II. We describe a new method by which a transient burst of turbulent vortex expansion can be generated in 3 He-B. It is based on the injection of a few vortex loops into rotating vortex-free flow. The time-dependent evolution of the quantized vortici...

A convenient method to create vortices in meta-stable vortex-free superflow of 3 He-B is to irradiate with thermal neutrons. The vortices are then formed in a rapid non-equilibrium process with very distinctive characteristics. Two models were suggested to explain the phenomenon. One is based on the Kibble-Zurek mechanism of defect formation in a quench-cooled second order phase transition. The...
متن کاملFast Vortex Core Switching at Moderate Temperatures
Ferromagnetic vortex core switching is investigated using micromagnetic simulations. For that the OOMMF program is used together with a temperature extension we have developed recently. This is a continuum micromagnetic approach, where the well-known Landau Lifshitz Gilbert equation (valid for zero temperature) is replaced by the Landau Lifshitz Bloch equation. In our research we simulate switc...

Turbulence in superfluids depends crucially on the dissipative damping in vortex motion. This is observed in the B phase of superfluid 3 He where the dynamics of quantized vortices changes radically in character as a function of temperature. An abrupt transition to turbulence is the most peculiar consequence. As distinct from viscous hydrodynamics, this transition to turbulence is not governed ...
