Specific heat of spin-3/2 transverse Ising model with the crystal field on honeycomb lattice

Physica Status Solidi B-Basic Research

The specific heat of the spin-3/2 transverse Ising model with the presence of a crystal field are studied by using the effective-field theory with correlations. In particular, the specific heat on a honeycomb lattice (z = 3) is examined in detail for the system. We find many interesting phenomena in the system.

PROTON SOLITON IN ANHARMONIC INTERACTION APPROXIMATION

Physics Letters A

We study the soliton model in the anharmonic interaction approximation for protons in hydrogen-bonded systems, and obtain analytical solutions of kink-antikink solitons. As compared with the harmonic interaction approximation, when the anharmonic counterpart is concluded, the symmetry of kink-antikink bonding solitons is broken, whereas the ionic solitons are almost unaffected.
