3D Ising Model on Dual BCC Lattice: the Sign-Factor
J. Ambjorn, Sh. Khachatryan, A. Sedrakyan
The 3d Ising model on a regular cubic lattice can be expressed in terms of an SU(2) 2d fermionic model with a -fluxes. We modify the model such that it is defined on the dual…

A New Family of Integrable Extended Multi-band Hubbard Hamiltonians
J. Ambjorn, A. Avakyan, T. Hakobyan +1
We consider exactly solvable 1d multi-band fermionic Hamiltonians, which have affine quantum group symmetry for all values of the deformation. The simplest Hamiltonian is a multi-b…
