A new approach to (quasi) periodic boundary conditions in micromagnetics: the macrogeometry

, 2009
We present a new method to simulate repetitive ferromagnetic structures. This macro geometry approach combines treatment of short-range interactions (i.e.

Effects of boundary conditions on magnetization switching in kinetic Ising models of nanoscale ferromagnets

, 1996
Magnetization switching in highly anisotropic single-domain ferromagnets has been previously shown to be qualitatively described by the droplet theory of metastable decay and simulations of two-dimensional kinetic Ising systems with periodic boundary ...

Spectral Properties of the Laplace Operator with Variable Dependent Boundary Conditions in a Disk

Axioms
In this work, we study the spectral properties of the Laplace operator with variable dependent boundary conditions in a disk. The boundary conditions include periodic and antiperiodic boundary conditions as well as the generalized Samarskii–Ionkin-type ...

Anti-Periodic Boundary Conditions in Supersymmetric DLCQ

, 2000
It is of considerable importance to have a numerical method for solving supersymmetric theories that can support a non-zero central charge. The central charge in supersymmetric theories is in general a boundary integral and therefore vanishes when one ...

A variational principle for complex boundary value problems

International Journal of Mathematics and Mathematical Sciences, 1988
This paper provides a variational formalism for boundary value problems which arise in certain feilds of research such as that of electricity, where the associated boundary conditions contain complex periodic conditions.

Stochastic Tamed 3D Navier-Stokes Equations: Existence, Uniqueness and Ergodicity

, 2009
In this paper, we prove the existence of a unique strong solution to a stochastic tamed 3D Navier-Stokes equation in the whole space as well as in the periodic boundary case.
