Abstract Superconductivity and superfluidity with anisotropic pairing—such as d-wave in cuprates and p-wave in superfluid 3He—are strongly suppressed by impurities. Meanwhile, for applications, the robustness of Cooper pairs to disorder is highly

Recent work has reported a realization of a time crystal in the form of the Bose-Einstein condensate of magnons in superfluid 3He. Here, the authors study the dynamics of a pair of such quantum time crystals and show that it closely resembles the evo

Symmetry-allowed topological defects, like quantized vortices, often control the universal behavior of macroscopic quantum systems. Here, Mäkinen et al. report survival of half-quantum vortices in symmetry-breaking transitions to polar-distorted pha

Based on Akama-Diakonov (AK) theory of emergent tetrads, it was suggested\cite{Volovik2023b} that one can introduce two Planck constants, which are the parameters of the corresponding components of Minkowski metric. In the AK theory, the interval $ds

The order parameter describing the spontaneous symmetry breaking which occurs when a system becomes a superfluid is analogous to the Higgs field in particle physics from which the Higgs boson arises. Here, the authors demonstrate the existence of a l

We discuss the possibility of torsional Nieh-Yan anomaly of the type ∂_{μ}(ej_{5}^{μ})=γT^{2}(T^{a}∧T_{a}) in Weyl superfluids, where T is the infrared (IR) temperature scale and T^{a} is the effective or emergent torsion from the superfluid o

A common property of topological systems is the appearance of topologically protected zero-energy excitations. In a superconductor or superfluid, such states set the critical velocity of dissipationless flow v_{cL}, proposed by Landau, to zero. We ch
