Nonlinear integral equations for the thermodynamics of the sl(4)-symmetric Uimin-Sutherland model
Jens Damerau, Andreas Klümper
We derive a finite set of nonlinear integral equations (NLIE) for the thermodynamics of the one-dimensional sl(4)-symmetric Uimin-Sutherland model. Our NLIE can be evaluated numeri…

Factorization of multiple integrals representing the density matrix of a finite segment of the Heisenberg spin chain
Herman E. Boos, Frank Göhmann, Andreas Klümper +1
We consider the inhomogeneous generalization of the density matrix of a finite segment of length of the antiferromagnetic Heisenberg chain. It is a function of the temperature…

Structural and magnetic instabilities of layered magnetic systems
Carsten Aits, Ute Löw, Andreas Klümper +1
We present a study of the magnetic order and the structural stability of two-dimensional quantum spin systems in the presence of spin-lattice coupling. For a square lattice it is s…
