Application of Fibonacci oscillators in the Debye model
(JOURNAL OF PHYSICS. CONFERENCE SERIES, 2014-12-08) Marinho, André A. A.; Brito, F. A.; Feitosa, Carlos Chesman de Araújo
In this paper we study the thermodynamics of a crystalline solid by applying q-deformed algebra of Fibonacci oscillators through the generalized Fibonacci sequence of two real and independent deformation parameters q1 and q2. We find a (q1, q2)-deformed Hamiltonian and consequently the q- deformed thermodynamic quantities. The results led us to interpret the deformation parameters acting as disturbance or impurities factors modifying the characteristics of a crystal structure. More specifically, we found the possibility of adjusting the Fibonacci oscillators to describe the change of thermal conductivity of a given element as one inserts impurites
