Effect of the random anisotropy disorder on pulsed NMR frequency shift in superfluid He-A in aerogel
نویسنده
چکیده
The anisotropic superfluid He-A in aerogel provides an interesting example of a system with continuous symmetry in the presence of random anisotropy disorder. Recent NMR experiments allows us to choose between different regimes of the orientational disorder.

Long-range Order in the A-like Phase of Superfluid 3He in Aerogel
Keywords Superfluid 3He, disorder and porous media Abstract A mutual action of the random anisotropy brought in the superfluid 3 He by aerogel and of the global anisotropy caused by its deformation is considered. Strong global anisotropy tends to suppress fluctuations of orientation of the order parameter and stabilizes ABM order parameter. In a limit of vanishing anisotropy fluctuations of ABM...

Liquid 3 He at low temperatures is an ideal substance to study because of its natural purity. The superfluid state, which appears at temperatures below 3 mK, has many unusual and exciting properties. These have extensively been studied experimentally, and the results are in many cases well understood theoretically using quasiclassical approximation. In this work we study the case that liquid 3 ...
متن کاملOn Larkin-Imry-Ma State of He-A in Aerogel
Superfluid He-A shares the properties of spin nematic and chiral orbital ferromagnet. Its order parameter is characterized by two vectors d̂ and l̂. This doubly anisotropic superfluid, when it is confined in aerogel, represents the most interesting example of a system with continuous symmetry in the presence of random anisotropy disorder. We discuss the Larkin-Imry-Ma state, which is characterize...
متن کاملStrong orientational effect of stretched aerogel on the (3)He order parameter.
Deformation of aerogel strongly modifies the orientation of the order parameter of superfluid (3)He confined in aerogel. We used a radial squeezing of aerogel to keep the orbital angular momentum of the (3)He Cooper pairs in the plane perpendicular to the magnetic field. We did not find strong evidence for a polar phase, with a nodal line along the equator of the Fermi surface, predicted to occ...
متن کاملSuperfluid Phase Stability of He in Axially Anisotropic Aerogel
Measurements of superfluid He in 98% aerogel demonstrate the existence of a metastable A-like phase and a stable B-like phase. It has been suggested that the relative stability of these two phases is controlled by anisotropic quasiparticle scattering in the aerogel. Anisotropic scattering produced by axial compression of the aerogel has been predicted to stabilize the axial state of superfluid ...
