Fractional quantum oscillator and disorder in the vibrational spectra

Autor: V. A. Stephanovich, E. V. Kirichenko, V. K. Dugaev, Jackie Harjani Sauco, Belén López Brito

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-12 (2022)

Abstract We study the role of disorder in the vibration spectra of molecules and atoms in solids. This disorder may be described phenomenologically by a fractional generalization of ordinary quantum-mechanical oscillator problem. To be specific, this

Existence and Approximation of Fixed Points of Enriched φ-Contractions in Banach Spaces

Autor: Vasile Berinde, Jackie Harjani, Kishin Sadarangani

Publikováno v: Mathematics, Vol 10, Iss 21, p 4138 (2022)

We introduce the class of enriched φ-contractions in Banach spaces as a natural generalization of φ-contractions and study the existence and approximation of the fixed points of mappings in this new class, which is shown to be an unsaturated class

Hartman–Wintner type inequalities for a class of fractional BVPs with higher order

Autor: Jackie Harjani, Kishin Sadarangani, Bessem Samet

Publikováno v: Journal of Inequalities and Applications, Vol 2019, Iss 1, Pp 1-12 (2019)

Abstract In this paper, we derive some Hartman–Wintner type inequalities for a certain higher order fractional boundary value problem. As an application of our results, we obtain a lower bound for the eigenvalues of the corresponding fractional ope
