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…

Lattice distortions in a sawtooth chain with Heisenberg and Ising bonds
Stefano Bellucci, Vadim Ohanyan
An exactly solvable model of the sawtooth chain with Ising and Heisenberg bonds and with coupling to lattice distortion for Heisenberg bonds is considered in the magnetic field. Us…

Antiferromagnetic sawtooth chain with Heisenberg and Ising bonds
Vadim Ohanyan
The sawtooth chain with pairs of spins interacting with -interactions placed on each second tooth is considered. All other interaction bonds are taken to be of Ising t…
