Quantum duality and Bethe - Ansatz for the Hofstadter problem on hexagonal lattice
نویسندگان
چکیده
The Hofstadter problem is studied on the hexagonal lattice. We first establish a relation between the spectra for the hexagonal lattice and for its dual lattice, the triangular lattice. Following the idea of Faddeev and Kashaev, we then obtain the Bethe-Ansatz equations for this system.

Exact solution for the spin-s XXZ quantum chain with non-diagonal twists
We study integrable vertex models and quantum spin chains with toroidal boundary conditions. An interesting class of such boundaries is associated with non-diagonal twist matrices. For such models there are no trivial reference states upon which a Bethe ansatz calculation can be constructed, in contrast to the well-known case of periodic boundary conditions. In this paper we show how the transf...
متن کاملQuantizing the Toda lattice
In this work we study the quantum Toda lattice, developing the asymptotic Bethe ansatz method first used by Sutherland. Despite its known limitations we find, on comparing with Gutzwiller’s exact method, that it works well in this particular problem and in fact becomes exact as \ grows large. We calculate ground state and excitation energies for finite-sized lattices, identify excitations as ph...
متن کاملBaxter-Wu model with general toroidal boundary conditions
The operator content of the Baxter-Wu model with general toroidal boundary conditions is calculated analytically and numerically. These calculations were done by relating the partition function of the model with the generating function of a site-colouring problem in a hexagonal lattice. Extending the original Bethe-ansatz solution of the related colouring problem we are able to calculate the ei...
متن کاملConnections of the Liouville Model and XXZ Spin Chain
The quantum theory of the Liouville model with imaginary field is considered using the Quantum Inverse Scattering Method. An integrable structure with nontrivial spectral parameter dependence is developed for lattice Liouville theory by scaling the L-matrix of lattice sine-Gordon theory. This L-matrix yields Bethe Ansatz equations for Liouville theory, by the methods of the algebraic Bethe Ansa...
متن کاملO ct 2 00 5 QUANTUM CURVE IN q - OSCILLATOR MODEL
A lattice model of interacting q-oscillators, proposed in [V. Bazhanov, S. Sergeev, arXiv:hep-th/0509181], is the quantum mechanical integrable model in 2+1 dimensional space-time. Its layer-to-layer transfer-matrix is a polynomial of two spectral parameters, it may be regarded in the terms of quantum groups both as a sum of sl(N) transfer matrices of a chain of length M and as a sum of sl(M) t...
