Toda–Heisenberg Chain: Interacting ?-Fields in Two Dimensions
نویسندگان
چکیده
We study a (2+1)-dimensional system that can be viewed as an infinite number of O(3) sigma-fields coupled by nearest-neighbour Heisenberg-like interaction. reduce the field equations this model to integrable is closely related two-dimensional relativistic Toda chain and Ablowitz-Ladik equations. Using reduction we obtain dark-soliton solutions our model.

Bundles of interacting strings in two dimensions
Bundles of strings which interact via short-ranged pair potentials are studied in two dimensions. The corresponding transfer matrix problem is solved analytically for arbitrary string number N by Bethe ansatz methods. Bundles consisting of N identical strings exhibit a unique unbinding transition. If the string bundle interacts with a hard wall, the bundle may unbind from the wall via a unique ...
متن کاملInteracting gauge fields and the zero-energy eigenstates in two dimensions
Gauge fields are formulated in terms of the zero-energy eigenstates of 2-dimensional Schrödinger equations with central potentials Va(ρ) = −agaρ (a 6= 0, ga > 0 and ρ = √ x2 + y2). It is shown that the zero-energy states can naturally be interpreted as a kind of interacting gauge fields of which effects are solved as the factors eigcχA , where χA are complex gauge functions written by the zero-...
متن کاملSpin-polarized ground state for interacting electrons in two dimensions.
We study numerically the ground state magnetization for clusters of interacting electrons in two dimensions in the regime where the single particle wave functions are localized by disorder. It is found that the Coulomb interaction leads to a spontaneous ground state magnetization. For a constant electronic density, the total spin increases linearly with the number of particles, suggesting a fer...
متن کاملMagnetic properties of interacting disordered electron systems in two dimensions
We compute the magnetic susceptibilities of interacting electrons in the presence of disorder on a twodimensional square lattice by means of quantum Monte Carlo simulations. Clear evidence is found that at sufficiently low temperatures disorder can lead to an enhancement of the ferromagnetic susceptibility. We show that it is not related to the transition from a metal to an Anderson insulator i...
متن کاملPeriodic Orbits in Magnetic Fields in Dimensions Greater than Two
The Hamiltonian flow of the standard metric Hamiltonian with respect to the twisted symplectic structure on the cotangent bundle describes the motion of a charged particle on the base. We prove that under certain natural hypotheses the number of periodic orbits on low energy levels for this flow is at least the sum of Betti numbers of the base. The problem is closely related to the existence qu...
