Local structure of ordered and disordered states of 3He-A in aerogel
arXiv:1707.04466 · doi:10.1103/PhysRevB.96.134203
Abstract
Random textures of the orbital part of the order parameter of superfluid 3He-A in aerogel are analyzed theoretically in the Ginzburg and Landau region both in the presence and in the absence of a global anisotropy. Correlation functions of angles, determining orientation of the order parameter are found for relative distances which are small in comparison with the characteristic scale of the random texture. Modifications of the Larkin-Imry-Ma state in limiting cases of a relatively strong uniaxial compression and of a uniaxial stretching are analyzed and characteristic parameters of the emerging states are found.
