Interaction of magnetic vortices with defects

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Manipulating microwaves with magnetic-dipolar-mode vortices

There has been a surge of interest in the subwavelength confinement of electromagnetic fields. It is well known that, in optics, subwavelength confinement can be obtained from surface plasmon (quasielectrostatic) oscillations. In this article, we propose to realize subwavelength confinement in microwaves by using dipolarmode (quasimagnetostatic) magnon oscillations in ferrite particles. Our stu...

The Stability of Magnetic Vortices

W e study the linearized stability of -vortex ( ) solutions of the magnetic Ginzb urg–Landau (or Abelian Higgs) equations. We prove that the fundamental vortices ( 1) are stable for all values of the coupling constant, , and we prove that the higher -degree vortices ( 2) are stable for 1, and unstable for 1. This resolves a long-standing conjecture (see, eg, [JT]).

Vortices and domain walls in a Chern - Simons theory with magnetic moment interaction

We study the structure and properties of vortices in a recently proposed Abelian Maxwell-Chern-Simons model in 2+1 dimensions. The model which is described by gauge field interacting with a complex scalar field, includes two parity and time violating terms: the Chern-Simons and the anomalous magnetic terms. Self-dual relativistic vortices are discussed in detail. We also find one dimensional so...
