Anomalous thermodynamics in a mixed spin-1/2 and spin-1 hexagonal nanowire system
R. A. Pimenta, O. Rojas, S. M. de Souza
The mixed spin-1/2 Ising model and spin-1 Blume-Capel model in an hexagonal nanowire structure under the presence of crystal field is considered. The free energy is obtained throug…

Free-parafermionic and free-fermionic quantum chains
Francisco C. Alcaraz, Rodrigo A. Pimenta
The relationship between the eigenspectrum of Ising and XY quantum chains is well known. Although the Ising model has a symmetry and the XY model a symmetry, both mod…

Scalar product for the XXZ spin chain with general integrable boundaries
Samuel Belliard, Rodrigo A. Pimenta, Nikita A. Slavnov
We calculate the scalar product of Bethe states of the XXZ spin- chain with general integrable boundary conditions. The off-shell equations satisfied by the transfer m…
