Superfluid He in Planar Aerogel
V. V. Dmitriev, M. S. Kutuzov, A. Y. Mikheev +3
We report results of experiments with liquid He confined in a high porosity anisotropic nanostructure which we call planar aerogel. This aerogel consists of nanofibers (with di…
Fundamental dissipation due to bound fermions in the zero-temperature limit
S. Autti, R. P. Haley, A. Jennings +7
The ground state of a fermionic condensate is well protected against perturbations in the presence of an isotropic gap. Regions of gap suppression, surfaces and vortex cores which…
Superfluid 3He in squeezed nematic aerogel
V. V. Dmitriev, M. S. Kutuzov, A. A. Soldatov +1
We present results of nuclear magnetic resonance (NMR) experiments in superfluid 3He in two samples of nematic aerogel consisting of nearly parallel mullite strands. The samples we…
NMR shifts in He in aerogel induced by demagnetizing fields
V. V. Dmitriev, M. S. Kutuzov, A. A. Soldatov +1
Magnetic materials generate demagnetizing field that depends on geometry of the sample and results in a shift of magnetic resonance frequency. This phenomenon should occur in porou…
