Generalized Morse Potential: Symmetry and Satellite Potentials [PDF]

Journal of Physics A: Mathematical and General, 1997
We study in detail the bound state spectrum of the generalized Morse potential~(GMP), which was proposed by Deng and Fan as a potential function for diatomic molecules.

Thermodynamics of DNA with “hump” Morse potential

Eclética Química, 2018
The thermal denaturation of DNA, i.e. the separation of the two strands is a phenomenon caused by the amplitude of the vibrations of the bases, therefore it is necessary to know how such separation is generated in order to implement alternative model of ...

Vibrational levels of a generalized Morse potential

The Journal of Chemical Physics, 2022
A Generalized Morse Potential (GMP) is an extension of the Morse Potential (MP) with an additional exponential term and an additional parameter that compensate for MP’s erroneous behavior in the long range part of the interaction potential. Because of the additional term and parameter, the vibrational levels of the GMP cannot be solved analytically ...

Analytical Bound-State solution of the Schrodinger equation for the morse potential within the Nikiforov-Uvarov method [PDF]

Mathematics and Computational Sciences, 2021
The Morse potential has important and significance rule to describe the diatomic molecule energy and structure. However there is no any analytical solution for Schrodinger equation with this potential without approximation, therefore other ways such as ...

Deformed Morse-like potential [PDF]

Journal of Mathematical Physics, 2021
We introduce an exactly solvable one-dimensional potential that supports both bound and/or resonance states. This potential is a generalization of the well-known 1D Morse potential where we introduced a deformation that preserves the finite spectrum property.

Wave motions along lattices with nonlinear on-site and inter-site potentials. Cooperation and/or competition leading to lattice solitons and/or discrete breathers; pp. 396–404 [PDF]

Proceedings of the Estonian Academy of Sciences, 2015
We consider the wave dynamics of a one-dimensional lattice where both on-site and inter-site vibrations, coupled together, are governed by Morse interactions.

Discrete kink dynamics in hydrogen-bonded chains I: The one-component model [PDF]

, 2002
We study topological solitary waves (kinks and antikinks) in a nonlinear one-dimensional Klein-Gordon chain with the on-site potential of a double-Morse type. This chain is used to describe the collective proton dynamics in quasi-one-dimensional networks

Effect of the velocity-dependent potentials on the energy eigenvalues of the Morse potential

Open Physics, 2012
Abstract We investigate the effect of the isotropic velocity-dependent potentials on the bound state energy eigenvalues of the Morse potential for any quantum states. When the velocity-dependent term is used as a constant parameter, ρ(r) = ρ 0, the energy eigenvalues can be obtained analytically by using the ...
