“…It was discovered in rotating NMR measurements, after a slow adiabatic first order 3 He-A ! 3 He-B transition had taken place in the rotating liquid [16]. Our new observations show that the spin-mass vortex is also formed in a rapid nonequilibrium quench through the second order transition from the normal phase to 3 He-B.…”

“…A second possibility is a similar process as that after which the spin-mass vortex was first observed [16]: In addition to the neutron absorption event, so far the only other effective method for forming spin-mass vortices in larger numbers is from A-phase vortex lines when the A ! B transition is allowed to propagate slowly through the rotating container.…”

“…For example, two-dimensional (2D) clusters can represent electrons in quantum dots [1] or on the surface of liquid helium [2], vortices in superfluids [4], colloidal particles in circular traps [5], confined ferromagnetic particles [6], and charged dust particles in plasma traps [7]. The 2D charged clusters also resemble the problem of charge distribution studied by Thomson in his "plum-pudding" model of the atom [8].…”

Structure and melting of two-species charged clusters in a parabolic trap

2003

We consider a system of charged particles interacting with an unscreened Coulomb repulsion in a two-dimensional parabolic confining trap. The static charge on a portion of the particles is twice as large as the charge on the remaining particles. The particles separate into a shell structure with those of greater charge situated farther from the center of the trap. As we vary the ratio of the number of particles of the two species, we find that for certain configurations, the symmetry of the arrangement of the inner cluster of singly-charged particles matches the symmetry of the outer ring of doubly-charged particles. These matching configurations have a higher melting temperature and a higher thermal threshold for intershell rotation between the species than the nonmatching configurations. [6], and charged dust particles in plasma traps [7]. The 2D charged clusters also resemble the problem of charge distribution studied by Thomson in his "plum-pudding" model of the atom [8].When confined to a parabolic trap, charged particles form a structure of concentric rings, with the inner particles forming a distorted triangular lattice resembling a defected Wigner crystal, and the outer rings taking on a more circular shape that conforms to the radial symmetry of the trap [9,10]. Among the possible charge configurations are several "magic" arrangements in which the number of particles is such that the shells form with only a few symmetrically distributed dislocations, and so have a reduced total energy compared to what is predicted based on a semi-empirical approximation [11]. Bubeck et al. [5] have observed that certain colloidal clusters confined by a circular hard-wall trap exhibit two-stage melting, in which intershell rotation between the outer two shells occurs at temperatures below the temperature at which particles are able to jump between the shells.Several explanations of this two-stage melting phenomenon have been proposed [9,[12][13][14], all of which focus on the intershell rotation which occurs prior to the exchange of particles between shells. Most plausible among these is the theory that the rotation is due to an incommensuration between the shapes of the potentials created by the adjacent shells. For this intershell rotation to occur, the inner shell configuration must be sufficiently stable to have a melting temperature higher than the threshold for intershell rotation.In our simulation, we extend the confined charge system to include particles with two distinct values of charge. We find that the two species separate into shells, with those of greater charge located farther from the center of the trap. This occurs due to the fact that the pinning force couples only to the position of the particle, while the interparticle repulsion is a function of both position and charge. Thus particles of greater charge are pushed farther up the walls of the parabolic trap. If two-stage melting and intershell rotation is caused by an incommensuration between the potentials formed by the particles, then we should be a...

“…It might be necessarily to introduce slow rotation while cooling through T C as was shown by Bevan et al [29]. The achievement represents a significant breakthrough not only for the study of chiral domain but also to visualize various topological objects in a topological superfluid, such as a spin-mass vortex [30], vortex sheet [31], and half-quantum vortex [32].…”

Chiral Domain Structure in SuperfluidHe3−AStudied by Magnetic Resonance Imaging

The existence of a spatially varying texture in superfluid 3He is a direct manifestation of the complex macroscopic wave function. The real space shape of the texture, namely, a macroscopic wave function, has been studied extensively with the help of theoretical modeling but has never been directly observed experimentally with spatial resolution. We have succeeded in visualizing the texture by a specialized magnetic resonance imaging. With this new technology, we have discovered that the macroscopic chiral domains, of which sizes are as large as 1 mm, and corresponding chiral domain walls exist rather stably in 3 He-A film at temperatures far below the transition temperature. DOI: 10.1103/PhysRevLett.120.205301 Modern interest in topological superfluids and superconductors has revived the significance of superfluid 3 He because of the most precisely understood macroscopic wave function of triplet p wave BCS superfluids. The topological nature of these quantum materials appears in connection to the boundary condition at the border and interface of the material. For a precise study on the topological properties, it is important to control the boundary conditions of the materials. The extremely precise understanding of the macroscopic wave function and its controllability of boundary conditions in real experimental situations makes superfluid 3 He an outstandingly suitable system for studying topological superfluids and superconductors. Specifically, the A phase of superfluid 3 He is regarded as a chiral superfluid because of the macroscopically aligned orbital angular momentum of its Cooper pairs [1,2]. Walmsley and Golov [3] were the first to show the existence of a macroscopically aligned orbital angular momentum in a thin slab of 3 He-A by using a torsional oscillator measurement in combination with a rotating ultralow temperature cryostat. Later, Ikegami et al. [4,5] obtained direct evidence of a bistability in the effect of the intrinsic Magnus force on electron transport in the vicinity of the free surface of a 3 He-A film. They also observed metastable intermediate states, which suggest the existence of a multidomain structure of macroscopically aligned orbital angular momentum. The proposed multidomain structure is nothing other than a chiral domain structure, consisting of macroscopic domains of monochirality and chiral domain walls between domains of opposite chirality. Naive consideration suggests the stability of a monochirality single domain structure because of the extra energy cost due to domain walls. As is discussed for the case of a p wave superconductor [6], a mesoscopic sample might have a multichiral domain structure. Some of the experimental studies on the possible chiral superconductor Sr 2 RuO 4 [7,8] have suggested the existence of a multichiral domain structure. The results indicated the existence of a chiral domain wall that separates the domains with opposite chirality. Walmsley et al. [9,10] also suggested the existence of domain walls in their torsional oscillator study to explain...
