Structure of surface vortex sheet between two rotating 3He superfluids
R. Hänninen, R. Blaauwgeers, V. B. Eltsov +4
We study a two-phase sample of superfluid 3He where vorticity exists in one phase (3He-A) but cannot penetrate across the interfacial boundary to a second coherent phase (3He-B). W…
Model of Inhomogeneous Impurity Distribution in Fermi Superfluids
R. Hänninen, E. V. Thuneberg
The standard treatment of impurities in metals assumes a homogeneous distribution of impurities. In this paper we study distributions that are inhomogeneous. We discuss in detail t…
Vortex lines or sheets - what is formed in dynamic drives?
V. B. Eltsov, R. Blaauwgeers, N. B. Kopnin +4
In isotropic macroscopic quantum systems vortex lines can be formed while in anisotropic systems also vortex sheets are possible. Based on measurements of superfluid 3He-A, we pres…
Calculation of NMR Properties of Solitons in Superfluid 3He-A
R. Hänninen, E. V. Thuneberg
Superfluid 3He-A has domain-wall-like structures, which are called solitons. We calculate numerically the structure of a splay soliton. We study the effect of solitons on the nucle…
Soliton-limited Superflow in 3He-A between Parallel Plates
J. Kopu, E. V. Thuneberg
We have studied theoretically the flow of superfluid 3He-A in parallel-plate geometry. The equilibrium order-parameter texture is calculated numerically in two spatial dimensions c…
One-Dimensional Textures and Critical Velocity in Superfluid 3He-A
J. Kopu, R. Hänninen, E. V. Thuneberg
We study theoretically the stability of flow in superfluid 3He-A. The calculations are done using a one-dimensional model where the order parameter depends only on the coordinate i…
Theory of the pi state in 3He Josephson junctions
J. K. Viljas, E. V. Thuneberg
The flow of superfluid 3He-B through a 65 x 65 array of nanometer size apertures has been measured recently by Backhaus et al. They find in the current--phase relation a new branch…
Periodic Vortex Structures in Superfluid 3He-A
J. M. Karimaki, E. V. Thuneberg
We discuss the general properties of periodic vortex arrangements in rotating superfluids. The different possible structures are classified according to the symmetry space-groups a…
Ginzburg-Landau Theory for Impure Superfluid 3He
E. V. Thuneberg
Liquid 3He 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 ex…
Models for Superfluid He in Aerogel
E. V. Thuneberg, S. K. Yip, M. Fogelström +1
Several recent experiments find evidence of superfluidity of 3He in 98%-porous aerogel. The primary effect of the aerogel is that it scatters the quasiparticles of 3He. We find tha…
