Quantum chains with GLq(2) symmetry

Usually quantum chains with quantum group symmetry are associated with representations of quantized universal algebras U q (g) . Here we propose a method for constructing quantum chains with C q (G) global symmetry , where C q (G) is the algebra of functions on the quantum group. In particular we will construct a quantum chain with GL q (2) symmetry which interpolates between two classical Ising chains.It is shown that the Hamiltonian of this chain satisfies in the generalised braid group algebra. 0
