چکیده
We develop a general scheme for the use of Fermi operators within the framework of integrable systems. This enables us to read off a fermionic Hamiltonian from a given solution of the YangBaxter equation and to express the corresponding L-matrix and the generators of symmetries in terms of Fermi operators. We illustrate our approach through a number of examples. Our main example is the algebraic Bethe ansatz solution of the Hubbard model in the infinite coupling limit.

Dissipation-driven integrable fermionic systems: from graded Yangians to exact nonequilibrium steady states
Using the Lindblad master equation approach, we investigate the structure of steadystate solutions of open integrable quantum lattice models, driven far from equilibrium by incoherent particle reservoirs attached at the boundaries. We identify a class of boundary dissipation processes which permits to derive exact steady-state density matrices in the form of graded matrix-product operators. All...
متن کاملSpectral Decomposition of Path Space in Solvable Lattice Model
We give the spectral decomposition of the path space of the Uq(ŝl2) vertex model with respect to the local energy functions. The result suggests the hidden Yangian module structure on the ŝl2 level l integrable modules, which is consistent with the earlier work [1] in the level one case. Also we prove the fermionic character formula of the ŝl2 level l integrable representations in consequence.
متن کاملSupersymmetric Representations and Integrable Fermionic Extensions of the Burgers and Boussinesq Equations
We construct new integrable coupled systems of N = 1 supersymmetric equations and present integrable fermionic extensions of the Burgers and Boussinesq equations. Existence of infinitely many higher symmetries is demonstrated by the presence of recursion operators. Various algebraic methods are applied to the analysis of symmetries, conservation laws, recursion operators, and Hamiltonian struct...

متن کاملW-Extended Logarithmic Minimal Models
We consider the continuum scaling limit of the infinite series of Yang-Baxter integrable logarithmic minimal models LM(p, p′) as ‘rational’ logarithmic conformal field theories with extendedW symmetry. The representation content is found to consist of 6pp′ − 2p− 2p′ W-indecomposable representations of which 2p+2p′ − 2 are of rank 1, 4pp′ − 2p− 2p′ are of rank 2, while the remaining 2(p− 1)(p′ −...
