Vortices In Density Wave Systems Subject To Transverse Electric Fields
نویسنده
چکیده
In this paper we predict many interesting new properties of vortices in highly anisotropic density wave systems subject to strong transverse electric fields. We mainly concentrate on ground state properties. Besides electric field-induced vortices we consider also thermally activated vortices. A new type of temperature-driven transition between two different phases of density waves in strong fields is predicted and several new properties of those phases are reported.

Electronic and Optical Properties of the Graphene and Boron Nitride Nanoribbons in Presence of the Electric Field
Abstract: In this study, using density functional theory and the SIESTA computationalcode, we investigate the electronic and optical properties of the armchair graphenenanoribbons and the armchair boron nitride nanoribbons of width 25 in the presence of atransverse external electric field. We have observed that in the absence of the electricfield, these structures are se...
متن کاملVortex dynamics in self-dual Maxwell-Higgs systems with a uniform background electric charge density.
We introduce selfdual Maxwell-Higgs systems with uniform background electric charge density and show that the selfdual equations satisfied by topological vortices can be reduced to the original Bogomol'nyi equations without any background. These vortices are shown to carry no spin but to feel the Magnus force due to the shielding charge carried by the Higgs field. We also study the dynamics of ...

Ab&act-The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The cutoff condition for transverse circularly polarized electromagnetic waves is obtained from the derived dispersion relation. The variation of the cutoff frequency CO,, w...
متن کاملParticle beams guided by electromagnetic vortices: new solutions of the Lorentz, Schrödinger, Klein-Gordon, and Dirac equations.
It is shown that electromagnetic vortices can act as beam guides for charged particles. The confinement in the transverse directions is due to the rotation of the electric and magnetic fields around the vortex line. A large class of exact solutions describing various types of relativistic beams formed by an electromagnetic wave with a simple vortex line is found both in the classical and in the...
متن کاملSatellite magnetic resonances of a bound pair of half-quantum vortices in rotating superfluid 3He-A.
The transverse magnetic resonance satellite frequency and intensity associated with a bound pair of half quantum vortices in a thin slab of 'He-A, rotating about the slab normal and subject to a magnetic field applied at an angle 0 with the slab normal, is recalculated in a variational approach. This approach takes properly into account the azimuthal symmetry of the spin wave function and there...
