Exact calculation of the magnetocaloric effect in the spin-1/2 XXZ chain

Christian Trippe, Andreas Honecker, Andreas Klümper +1

We calculate the entropy and cooling rate of the antiferromagnetic spin-1/2 XXZ chain under an adiabatic demagnetization process using the quantum transfer-matrix technique and non…

Short-distance thermal correlations in the massive XXZ chain

Christian Trippe, Frank Göhmann, Andreas Klümper

We explore short-distance static correlation functions in the infinite XXZ chain using previously derived formulae which represent the correlation functions in factorized form. We…
