Motivated by the recent observation and argument on a large half-quantum vortex (HQV) pair connencted by a Kibble wall in superfluid 3He in nematic aerogels, we numerically study to what extent a huge HQV pair can intrinsically occur with no pinning effect due to the aerogel structure in the polar-distorted B (PdB) phase of superfluid 3He. By fully examining the impurity-scattering induced pairing vertex, the emergence of Anderson's Theorem in the p-wave superfluid is verified in the two… 
Half-quantum vortices in nematic and chiral phases of He3
We report theoretical results for the stability of half-quantum vortices (HQVs) in the superfluid phases of 3He confined in highly anisotropic Nafen aerogel. Superfluidity of 3He confined in Nafen is
Impact of strong anisotropy on the phase diagram of superfluidHe3in aerogels
Recently, one analog of the Anderson's Theorem for the $s$-wave superconductor has attracted much interest in the context of the $p$-wave polar pairing state of superfluid $^3$He in a model aerogel

TLDR
A quantized vortex spontaneously breaks its axisymmetry, leading to an elliptic vortex in nematic-spin Bose-Einstein condensates with small positive quadratic Zeeman effect, which is considered the Joukowski transform of a conventional vortex.
Fibration, Nexus and Cosmological Composite Topological Defects in Uniaxially Disordered Superfluid $^3$He
The composited cosmological defects in superfluids of nafen-disorded 3He are discussed in this review article. In spite of the existence of the half quantum vortices (Alice strings), more novel
One-dimensional nexus objects, network of Kibble-Lazarides-Shafi string walls, and their spin dynamic response in polar-distortedB-phase ofHe3
The Kibble-Lazarides-Shafi (KLS) domain wall problem in the axion solution of CP violation in QCD has condensed-matter based analogy in the nafen-distorted superfluid $^3$He. Recent experiment in
String monopoles, string walls, vortex skyrmions, and nexus objects in the polar distorted B phase of He3
The composite cosmological objects -- Kibble-Lazarides-Shafi (KLS) walls bounded by strings and cosmic strings terminated by Nambu monopoles -- could be produced during the phase transitions in the

Stability of half-quantum vortices in equal-spin pairing states of He3
Recent experiments on superfluid $^3$He in globally anisotropic aerogels have shown realization of the polar superfluid phase and of the half-quantum vortices (HQVs) in this phase upon rotation. To

TLDR
It is shown that half-quantum vortices—linear topological defects carrying half quantum of circulation—survive transitions from the polar phase to other superfluid phases with polar distortion in nanostructured confinement 3He.

TLDR
The Ginzburg-Landau theory of vortices reproduces the properties of the Transition, accounts well for the measured susceptibility and magnetization, and gives detailed predictions about properties not yet measured, such as the jump of the magnetization in the transition, the shift of the transition line in magnetic field, and the orientation of the double-core vortex.

TLDR
This work applies the spectrum of fermion states localized within the vortex core of a weak-coupling p-wave superfluid to the rotational dynamics of vortices in superfluid ^{3}He-B and finds an explanation for the observed slow mode.
