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…
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…
Spin diffusion in liquid He confined in planar aerogel
V. V. Dmitriev, M. S. Kutuzov, L. A. Melnikovsky +3
We report the results of theoretical and experimental investigation of spin diffusion in the normal phase of liquid He confined in planar aerogel: a material consisting of nano…
Half-quantum vortices and walls bounded by strings in the polar-distorted phases of topological superfluid He
J. T. Mäkinen, V. V. Dmitriev, J. Nissinen +5
Symmetries of the physical world have guided formulation of fundamental laws, including relativistic quantum field theory and understanding of possible states of matter. Topologica…
