Chiral edge modes in Helmholtz-Onsager vortex systems

چکیده
Vortices play a fundamental role in the physics of two-dimensional (2D) fluids across range length scales, from quantum superfluids to geophysical flows. Despite history dating back Helmholtz, point vortices 2D fluid continue pose interesting theoretical problems, owing their unusual statistical mechanics. Here we show that strongly interacting Helmholtz-Onsager vortex systems can form edge modes at low energies, extending previously identified analogy between matter and Hall systems. Through dynamical simulations, Monte-Carlo sampling, mean-field theory, demonstrate these are associated with formation dipoles real image boundaries. The robust, persisting nonconvex domains, quantitative agreement predictions.1 MoreReceived 1 March 2021Accepted 11 June 2021DOI:https://doi.org/10.1103/PhysRevFluids.6.064702©2021 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasVortex flowsVortices superfluidsPhysical SystemsClassical fluidsHamiltonian systemsQuantum & solidsFluid DynamicsStatistical Physics

Inertia and chiral edge modes of a Skyrmion magnetic bubble.
The dynamics of a vortex in a thin-film ferromagnet resembles the motion of a charged massless particle in a uniform magnetic field. Similar dynamics is expected for other magnetic textures with a nonzero Skyrmion number. However, recent numerical simulations reveal that Skyrmion magnetic bubbles show significant deviations from this model. We show that a Skyrmion bubble possesses inertia and d...
متن کاملChiral Second-Sound Collective Modes at the Edge of 2D Systems with a Nontrivial Berry Curvature.
We study the thermal transport in two-dimensional systems with a nontrivial Berry curvature texture. The physical realizations are many; for the sake of definiteness, we consider undoped graphene gapped by the presence of an aligned hexagonal-boron-nitride substrate. The same phenomenology applies, i.e., to surface states of 3D topological insulators in the presence of a uniform magnetization. ...
متن کاملVortex in Chiral Superconducting State
We have investigated the vortex in chiral superconductors, especially in p-wave case. In chiral superconductors the Cooper pair has orbital angular momentum hence U (1), parity (P) and time reversal symmetry (T) are broken simultaneously. We have found that the vortex has fractional charge and fractional angular momentum which comes from P-and T-violation. The fractionalization of the angular m...
متن کاملMagnetization Reversal Modes in Short Nanotubes with Chiral Vortex Domain Walls
Micromagnetic simulations of magnetization reversal were performed for magnetic nanotubes of a finite length, L, equal to 1 and 2 μm, 50 and 100 nm radii, R, and uniaxial anisotropy with "easy axis" parallel to the tube length. I.e., we considered relatively short nanotubes with the aspect ratio L/R in the range 10-40. The non-uniform curling magnetization states on both ends of the nanotubes c...
متن کاملEdge states in graphene: from gapped flat-band to gapless chiral modes.
We study edge states in graphene systems where a bulk energy gap is opened by inversion symmetry breaking. We find that the edge bands dispersion can be controlled by potentials applied on the boundary with unit cell length scale. Under certain boundary potentials, gapless edge states with valley-dependent velocity are found, exactly analogous to the spin-dependent gapless chiral edge states in...
