Correlation functions in one-dimensional spin lattices with Ising and Heisenberg bonds
Stefano Bellucci, Vadim Ohanyan
A general technique of exact calculation of any correlation functions for the special class of one-dimensional spin models containing small clusters of quantum spins assembled to a…
Exact description of the magnetoelectric effect in the spin-1/2 XXZ-chain with Dzyaloshinskii-Moriya interaction
Michael Brockmann, Andreas Klümper, Vadim Ohanyan
We consider a simple integrable model of a spin chain exhibiting the Magnetoelectric Effect (MEE). Starting from the periodic S=1/2 XXZ-chain with Dzyaloshinskii-Moriya terms, whic…
Magnetocaloric effect in spin-1/2 chains with three-spin interactions
Myroslava Topilko, Taras Krokhmalskii, Oleg Derzhko +1
We consider the exactly solvable spin-1/2 chain with the three-spin interactions of the and types in an external (transverse) magnetic field. We calculate…
Magneto-thermal properties of the Heisenberg-Ising orthogonal-dimer chain with triangular XXZ-clusters
Vadim Ohanyan, Andreas Honecker
We study a spin-1/2 model with triangular XXZ-clusters on the orthogonal-dimer chain in the presence of an external magnetic field. First, we discuss the case where the triangular…
