Motion of vortices in ferromagnetic spin-1 BEC
E. B. Sonin
The paper investigates dynamics of nonsingular vortices in a ferromagnetic spin-1 BEC, where spin and mass superfluidity coexist in the presence of uniaxial anisotropy (linear and…
Dynamics of helical vortices and helical-vortex rings
E. B. Sonin
The Letter considers dynamics of helical vortices and helical-vortex rings either solving directly the equations of motions of a vortex line or using canonical relations following…
Effect of Klein tunneling on conductance and shot noise in ballistic graphene
E. B. Sonin
The conductance and the Fano factor in a graphene sheet in the ballistic regime are calculated. The electrostatic potential in the sheet is modeled by a trapezoid barrier, which al…
Domain-Wall Waves (2D Magnons) in Superconducting Ferromagnets
N. A. Logoboy, E. B. Sonin
Propagation of the magnetization waves along domain walls (2D magnons) in a superconducting ferromagnet has been studied theoretically. The magnetostatic fields (long-range dipole-…
Orbital magnetic dynamics in chiral p-wave superconductors
V. Braude, E. B. Sonin
We present a theory of orbital magnetic dynamics for a chiral p-wave superconductor with broken time-reversal symmetry. In contrast to the common Landau-Lifshitz theory for spin fe…
Domain structure of superconducting ferromagnets
E. B. Sonin
In superconducting ferromagnets the equilibrium domain structure is absent in the Meissner state, but appears in the spontaneous vortex phase (the mixed state in zero external magn…
Multiwalled carbon nanotube: Luttinger liquid or not?
R. Tarkiainen, M. Ahlskog, J. Penttilä +4
We have measured IV-curves of multiwalled carbon nanotubes using end contacts. At low voltages, the tunneling conductance obeys non-Ohmic power law, which is predicted both by the…
Josephson-plasma and vortex modes in layered superconductors
E. B. Sonin
The Josephson-plasma and vortex modes in layered superconductors have been studied theoretically for low magnetic fields parallel and perpendicular to layers. The two modes belong…
"Superconductor-Insulator transition" in a single Josephson junction
J. S. Penttila, U. Parts, P. J. Hakonen +2
VI-curves of resistively shunted single Josephson junctions with different capacitances and tunneling resistances are found to display a crossover between two types of VI-curves: o…
The Magnus force in superfluids and superconductors
E. B. Sonin
The forces on the vortex, transverse to its velocity, are considered. In addition to the superfluid Magnus force from the condensate (superfluid component), there are transverse fo…
