متن کاملTopological-Torsion and Topological-Spin as coherent structures in plasmas
The PDE’s of classical electromagnetism can be generated from two exterior differential systems that distinguish topologically the field intensities and potentials, F − dA = 0, from the field excitations and the charge current densities, J − dG = 0. The existence of potentials, A, leads to the independent 3-forms of T-Torsion = AˆF and T-Spin = AˆG. The exterior derivatives (divergences) of the...
متن کاملMagnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice
Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.
متن کاملLattice Structures and Spreading Models
We consider problems concerning the partial order structure of the set of spreading models of Banach spaces. We construct examples of spaces showing that the possible structure of these sets include certain classes of finite semi-lattices and countable lattices and all finite lattices.
متن کاملTopological modes in dual lattice models.
Lattice gauge theory with gauge group ZP is reconsidered in four dimensions on a simplicial complex K. One finds that the dual theory, formulated on the dual block complex K̂, contains topological modes which are in correspondence with the cohomology group H2(K̂, ZP ), in addition to the usual dynamical link variables. This is a general phenomenon in all models with single plaquette based actions...
