We use a system of deformed harmonic oscillators with complex deformation parameter to describe, by means of a q-deformed analogous to the Debye model, a solid subjected to external perturbations or with some nonlinear effects inside the lattice. In the case of a weak deformation, the specific heat of the lattice exhibits a departure from the standard behavior only at low temperatures, whereas the usual Dulong-Petit law is recovered in the high-temperature limit.

Abstract: | We use a system of deformed harmonic oscillators with complex deformation parameter to describe, by means of a q-deformed analogous to the Debye model, a solid subjected to external perturbations or with some nonlinear effects inside the lattice. In the case of a weak deformation, the specific heat of the lattice exhibits a departure from the standard behavior only at low temperatures, whereas the usual Dulong-Petit law is recovered in the high-temperature limit. | |
