Microscopic conservation laws for integrable lattice models
نویسندگان
چکیده
We consider two discrete completely integrable evolutions: the Toda Lattice and Ablowitz–Ladik system. The principal thrust of paper is development microscopic conservation laws that witness perturbation determinant under these dynamics. In this way, we obtain analogues objects found essential in our recent analyses KdV, NLS, mKdV. concert with this, revisit classical topic attendant to (renormalized) trace Green’s function.

On integrable conservation laws.
We study normal forms of scalar integrable dispersive (not necessarily Hamiltonian) conservation laws, via the Dubrovin-Zhang perturbative scheme. Our computations support the conjecture that such normal forms are parametrized by infinitely many arbitrary functions that can be identified with the coefficients of the quasi-linear part of the equation. Moreover, in general, we conjecture that two...
متن کاملIntegrable Lattice Models for Conjugate A
A new class of A (1) n integrable lattice models is presented. These are interaction-round-a-face models based on fundamental nimrep graphs associated with the A (1) n conjugate modular invariants, there being a model for each value of the rank and level. The Boltzmann weights are parameterized by elliptic theta functions and satisfy the Yang-Baxter equation for any fixed value of the elliptic ...
متن کاملConservation Laws of Turbulence Models
Conservation of mass, momentum, energy, helicity, and enstrophy in fluid flow are important because these quantities organize a flow, and characterize change in the flow’s structure over time. Thus, if a simulation of a turbulent flow is to be qualitatively correct, these quantities should be conserved in the simulation. However, such simulations are typically based on turbulence models whose c...
متن کاملScalar Non-linear Conservation Laws with Integrable Boundary Data
We consider the initial-boundary value problem for a scalar non-linear conservation law u t + f(u)] x = 0; u(0; x) = u(x); u(; 0) = ~ u(t); () on the domain = f(t; x) 2 R 2 : t 0; x 0g. Here u = u(t; x) is the state variable, u; ~ u are integrable (possibly unbounded) initial and boundary data, and f is assumed to be strictly convex and superlinear. We rst derive an explicit formula for a solut...
متن کاملConservation laws and bosonization in integrable Luttinger liquids.
We examine and explain the Luttinger-liquid character of models solvable by the Bethe ansatz by introducing a suitable bosonic operator algebra. In the case of the Hubbard chain, this involves two bosonic algebras which apply to all values of U , electronic density, and magnetization. Only at zero magnetization does this lead to the usual charge spin separation. We show that our “pseudoparticle...
