Magnetic Domains

TLDR
In this paper, a Nahm transform has been discovered for magnetic bags, which are conjectured to arise in the large n limit of magnetic monopoles with charge n, and they are interpreted using string theory and presented some partial proofs of this conjecture.
Abstract
Recently a Nahm transform has been discovered for magnetic bags, which are conjectured to arise in the large n limit of magnetic monopoles with charge n We interpret these ideas using string theory and present some partial proofs of this conjecture We then extend the notion of bags and their Nahm transform to higher gauge theories and arbitrary domains Bags in four dimensions conjecturally describe the large n limit of n self-dual strings We show that the corresponding Basu-Harvey equation is the large n limit of an equation describing n M2-branes, and that it has a natural interpretation in loop space We also formulate our Nahm equations using strong homotopy Lie algebras

Spin-polarized Current-driven Ferromagnetic Domain Wall Motion with a Skyrmion Building Block

TL;DR: In this paper, the authors constructed an analytical model for describing spin-polarized current-driven ferromagnetic domain wall motion with a skyrmion building block and found that the dependence of velocity of the wall motion was found as a function of driving torques and an external magnetic field strength.

Asymptotic shape of isolated magnetic domains

TL;DR: In this paper , the energy of an isolated magnetized domain Ω⊂Rn for n = 2,3 was investigated and the solutions for the compactness and Γ-limit problems were derived in terms of the cross-sectional area of the anisotropic rescaled configuration.

Magnetic Studies of Vapor-Deposited Co/Si(100) and Co/Glass Thin Films

TL;DR: Magnetic force microscopy and alternating gradient field magnetometry techniques were used to investigate the static magnetic properties of vapor-deposited cobalt films with different thicknesses ranging from 50 to 195 nm as discussed by the authors.

Cluster Reverberation: a mechanism for robust short-term memory without synaptic learning

TL;DR: It is shown how a sufficiently clustered network of simple model neurons can be instantly induced into metastable states capable of retaining information for a short time and could constitute a viable mechanism available to the brain for robust short-term memory with no need of synaptic learning.

Magnetic ground and remanent states of synthetic metamagnets with perpendicular anisotropy

TL;DR: In this paper, a phenomenological micromagnetic approach for magnetic ground state and nonequilibrium states as topological magnetic defects in multilayers with strong perpendicular anisotropy and antiferromagnetic (AF) interlayer exchange coupling (IEC), e.g. [Co/Pt(Pd)]/Ru(Ir, NiO), is presented.

Gauge symmetry and supersymmetry of multiple M2-branes

TL;DR: In this article, a supersymmetric field theory model for multiple M2-branes based on an algebra with a totally antisymmetric triple product is proposed. But the field is not dynamical.

Dielectric-Branes

TL;DR: In this paper, the authors extend the usual action for a Dp-brane to the case of N coincident Dpbranes where the world-volume theory involves a U(N) gauge theory.

Type iib superstrings, bps monopoles, and three-dimensional gauge dynamics

TL;DR: In this article, the Coulomb branch of certain three-dimensional supersymmetric gauge theories and the moduli spaces of magnetic monopoles are explained via string theory, and new phase transitions in three dimensions as well as new infrared fixed points and even new coupling constants are predicted from the string theory construction.
