High frequency critical attenuation of sound in He3-He4 mixtures near T

2014 We have measured the critical attenuation of sound at 1.1 GHz in He3-He4 mixtures of 0.06, 0.20 and 0.24 molar He3 concentrations. The results above the superfluid-normal transition are scaled with the same scaling function used in the kHz frequency range for pure He4.

Magnetic Field Influence on Critical Sound Attenuation and Velocity Variation in Ferromagnets

The ultrasound velocity and attenuation are investigated in ferromagnets under an application of magnetic field. In the magnetic field six different characteristic regimes are distinguished instead of traditional two (hydrodynamic and critical) found for the case of zero magnetic field. The mean-field Landau–Khalatnikov theory as well as the scaling predictions are given for each regime. Variou...

Visualizing Dynamical Systems near Critical Points

In this paper we present two visualization techniques. One uses the topological structure of the dynamical system near critical points to build an abstract description of the ow. The other places bunches of streamlets around the critical points to visualize the ow characteristics locally. Combining both methods a powerful visualization technique is present, since both the topological informatio...

Dynamics and Transport near Quantum-critical Points

The physics of non-zero temperature dynamics and transport near quantum-critical points is discussed by a detailed study of the O(N)symmetric, relativistic, quantum field theory of a N -component scalar field in d spatial dimensions. A great deal of insight is gained from a simple, exact solution of the long-time dynamics for the N = 1 d = 1 case: this model describes the critical point of the ...

Disordered systems near quantum critical points

Various aspects of disordered systems at and near quantum phase transitions (QPT), which are transitions at zero temperature that are driven by quantum instead of thermal uctuations, are discussed. We describe a cluster algorithm in continuous (imaginary) time for general (pure or random) ferromagnetic Ising models in a transverse eld. It works directly with an innnite number of time-slices in ...
