Abstract:Some empirical results on the cubic algebra 2a { = Σ [#/, [#/> ^]] are j presented. The algebra is satisfied at the residue of any pole in a solution to Nahm's non-self-dual equations.
“…This theory can be embedded in an enveloping multidimensional theory: the Atiyah-Drinfeld-Hitchin-Manin-Nahm construction may then appear as the condition for the equivalence between two sets of self-dual equations, one as described above in one dimension and the other in three dimensions [4]. Such a one-dimensional model is a particular case (m = 0) of another well-known model, the Ginzburg-Landau (GL) model, also known as the phi-in-quadro (φ 4 ) model, widely applied in phase transition theory.…”

“…This function corresponds to the Weierstrass function with the invariants g 2 = b 4 and g 3 = 0, which leads directly to the solution in the form presented in [4]. In the case of the Nahm model, the quantum correction allows evaluating the Yang-Mills field mass in the semiclassical approximation.. We use the expression for the potential in terms of solution (18),…”

We consider one-dimensional Yang-Mills-Nahm and sine-Gordon models in terms of a class of nonlinear Klein-Gordon-Fock equations. We perform a semiclassical quantization of the models using a generalized zeta function and construct a representation of the quantum theory in terms of the diagonal of the Green's function for the heat equation with an elliptic potential via solutions of the Hermite equation. We formulate an alternative approach based on Baker-Akhiezer functions for the KP equation. We evaluate quantum corrections to the action of the Nahm and sine-Gordon models. We study the fields from the class of elliptic functions. We take extra variables of arbitrary dimensions into account for possible applications of quantized sine-Gordon solitons in solid state physics via the Frenkel-Kontorova model or other models. For the Nahm model, whose field is represented via an elliptic (lemniscate) integral by construction, the Yang-Mills field mass coincides with the correction evaluated as a hyperelliptic integral.

“…where L 0 is a generator of the Virasoro algebra with conformal weight c = 1 that can be canonically obtained from the U(1) Kac-Moody algebra using the Sugawara construction [35]. Here q is the eigenvalue of T 0 , and the highest weight representation is [∆, q].…”
The spectrum of the non-hermitian asymmetric XXZ-chain with additional non-diagonal boundary terms is studied. The lowest lying eigenvalues are determined numerically. For the ferromagnetic and completely asymmetric chain that corresponds to a reaction-diffusion model with input and outflow of particles the smallest energy gap correponding directly to the inverse of the temporal correlation length shows the same properties as the spatial correlation length of the stationary state. For the antiferromagnetic chain with both boundary terms, we find a conformal invariant spectrum where the partition function corresponds to the one of a Coulomb gas with only magnetic charges shifted by a purely imaginary and a lattice-length dependent constant. Similar results are obtained by studying a toy model that can be diagonalized analytically in terms of free fermions.
“…Теория поля Янга-Миллса обладает помимо всего прочего редукциями к одномерным моделям [3]. Также возможно вложить эту теорию в объемлющую многомерную теорию: конструкция Атьи-Дринфельда-Хитчина-Манина-Нама при этом может возникать в качестве условия эквивалентности между двумя наборами уравнений самодуальности: в размерности 1, как описано выше, и в размерности 3 [4]. Одномерная модель представляет собой частный случай (m = 0) другой хорошо известной модели, а именно модели Гинзбурга-Ландау (ГЛ), также известной как φ 4 -модель, широко применяемой в теории фазовых переходов.…”
