Approximation solutions of time dependent Schrodinger equation for Eckart potential using the Nikiforov-Uvarov-Functional Analysis method
The time dependent Schrödinger equation for The Eckart potential is studied. This potential is not studied in the literatures. The Eckart potential is a superposition of the Coulomb potential and the Yukawa potential. The Eckart potential is a diatomic molecular potential model widely used in applied Physics and chemical Physics. To obtain the energies spectrum and the wave functions we use a new method called Nikiforov–Uvarov-Functional Analysis (NUFA) method and the method of variables separation. The (NUFA) method is composed of the concepts of the Nikiforov-Uvarov (NU) method, the parametric Nikiforov-Uvarov method and the functional analysis method. This method is a simple and elegant method for solving a second order differential equation of the hypergeometric type. This method is easy and simple just as the parametric NU method. Unlike the NU method which involved looking for the square of the polynomials and other conditions which makes it complicated, the (NUFA) method can easily be used to obtain the energy and the wave function once the wave equations have been properly transformed and the singularities identified. So its simplicity eliminates the rigorous mathematical manipulations, as encountered in other techniques. This method can be used to solve few body problems in nuclear physics, particle physics, as well as molecular and chemical physics.

Quantum study for hydrogenoid atoms in non-commutative space
The non-commutative geometry is a geometry where the coordinates of space-phase do not commute; it was designed both to meet needs in mathematics and to allow treating some theoretical physics problems . The noncommutativity was introduced firstly by Heisenberg W. in 1930 and then developed and formulated by Syndre H. in 1947 because of the need to regularize the divergence of the quantum field theory . Recently, physicists have developed previously works by applying the noncommutativity properties on space and phase . The noncommutativity get more investigation in the microscopic scales and achieve more scientific knowledge of elementary particles in the field of nanotechnology, and it is shown a direct relationship between string theory and noncommutative geometry and to obtaining profound and new applications for different areas of matter sciences in the microscopic and nano scales within the framework of quantum mechanics and quantum field theory . The aim of this work is to study the hydrogenoid atoms in a noncommutative space, this noncommutativity was considered as a time-independent perturbation in the expression of the Coulomb potential. I then made some resulting corrections in the expression of Bohr energies and fine structure energies. I came to a conclusion that the noncommutativity lifted the degeneracy of the energies, and induced a shift in the spectrum of the energies. Keywords: Schrödinger equation, the hydrogenoid atom, Coulomb potential, noncommutative space-phase, the Weyl Moyal star product, the Bopp’s shift method.

Arbitrary l state solutions of the Klein Gordon equation with Hellmann generalized Morse potential
The approximate analytical solutions of the radial Klein –Gordon equation have been obtained with a equally scalar and vector of newly proposed potential called Hellmann-generalized Morse potential. The potential is a superposition of Hellmann potential and generalized Morse or Deng-Fan potential. The Hellmann-generalized Morse potential actually comprises of three different potentials which includes Yukawa potential, Coulomb potential and Deng-Fan potential. The aim of combining these potentials is to have a wide application. The energy eigenvalues and the corresponding wave functions are calculated in a closed and compact form using the parametric Nikiforov-Uvarov method. The Nikiforov–Uvarov method which is based on solving the second-order linear differential equations by reduction to a generalized equation of hypergeometric type is used to obtain exact energy eigenvalues and corresponding normalized eigenfunctions.

Quantum study of the one dimensional Coulomb potential with a time dependent electrical charge
In This work we studied the exact solutions of the one dimensional Schrödinger equation with a time-dependent Coulomb potential (-Z(t)/|x|) based on the formalism of quantum invariant theory ( Lewis and Riesenfeld theorem). Using the technique of unitary transformation with a relevant choice of an invariant operator, we have obtained the eigenfunctions and the corresponding energy eigenvalues of the system. Due to the singularity at the origin, solutions are obtained separately for the region x>0 and x<0, and then matched appropriately at x=0. The solution of the problem here is expressed in terms of associated Laguerre functions (regular solution), z(t)=z₀ our wavefunction is fully equivalent to the 3D Hydrogen problem in the case of the zero angular momentum which nullifies the centrifugal potential terms. The results we examined for this potential are comparable to those obtained in the stationary case. Keywords : Coulomb potential; Schrödinger equation; Dynamical invariant; wavefunctions.

Dynamical Invariant and Exact Mechanical Analyses for the Caldirola–Kanai Model of Dissipative Three Coupled Oscillators
We study the dynamical invariant for dissipative three coupled oscillators mainly from the quantum mechanical point of view. It is known that there are many advantages of the invariant quantity in elucidating mechanical properties of the system. We use such a property of the invariant operator in quantizing the system in this work. To this end, we first transform the invariant operator to a simple one by using a unitary operator in order that we can easily manage it. The invariant operator is further simplified through its diagonalization via three-dimensional rotations parameterized by three Euler angles. The coupling terms in the quantum invariant are eventually eliminated thanks to such a diagonalization. As a consequence, transformed quantum invariant is represented in terms of three independent simple harmonic oscillators which have unit masses. Starting from the wave functions in the transformed system, we have derived the full wave functions in the original system with the help of the unitary operators.

The exact solution of the stationary and non stationary Schrodinger equation for bidimensional harmonic oscillators in non-commutative space-phase
We have obtained the exact solution of the time-independent and time-dependent Schrodinger equation governing the two dimensional harmonic oscillator in non-commutative space-phase. We write the Hamiltonian of the system in terms of creation and annihilation operators(a_i,a_i^+), and then we solve the time-independent and time-dependent Schrodinger equation under the condition M(t)Ω(t)=const. For the stationary Schrodinger equation we use the algebraic method. For non stationary Schrodinger equation we use the Lewis-Riesenfeld invariant theory and the invariant-related unitary transformation formulation.

Exact solution of the non stationary Schrodinger equation for one dimensional the inverse square root potential
The non stationary Schrodinger equation is exactly solved for the one dimensional inverse square root potential: V(x,t)=V_0 (t)/√x. To solve this equation we use the invariant method. Each of the two fundamental solutions that compose the general solution of the problem is giving by a combination with the non-constant coefficients of two confluent hypergemetric functions of a shift argument. Alternatively, the solution is written through the first derivative of a tri-confluent Heun function. The spectrum energy is giving by: E_n (t)=E_1 (t) n^(-2/3) .

Quantum features of molecular interactions associated with time dependent non-central potentials
The research for quantum future of molecular Coulomb interactions subjected to a time-dependent non-central potential has many applications. The wave function of this system can be ontained by using an invarian operator, which is necessary for investigating a time-dependent Hamiltonian system. regarding time dependence of the system, one can confirm that the formula of this operator is in general somewhat complicated. Hence, in order to solve its eigenvalue equation, special mathematical techniques beyond separation of variables method, such as the unitary transfomation method, the Nikiforov-Uvarov method, and the asymtotic iteration method, should be employed . The double ring-shaped generalized non central potetial of which evolution explicity depends on time is introduced as a particular case. The complete quatum solutions of the system can be identifed from the eigenstatess of the invarian operator. Thes solutions are useful for analysing dynamical properties of the system

the validity of the Ehrenfest theorem beyond simple static systems: Caldirola-Kanai oscillator driven by a time-dependent force
The relashionship between quantum mechanics and classical mechanics is investigated by taking a Gaussian-type wave packet as a solution of the Schrodinger equation for the Caldirola-Kanai oscillator driven by a sinusoidal force. For this time-dependent system, quantum properties are studied using the invariant theory of Lewis and Riesenfeld . In particular, we analyse time behaviours of quantum expectation values of position and momentum variables and compare them to those of the counterpart classical ones. Based on this, we check whether the Ehrenfest theorem which was originally developed in static quantum systems can be extended to such time-varying systems without problem. Keywords: Ehrenfest theorem, invariant theory, time dependent Hamiltonian system

of 3D nonstationary harmonic plus inverse harmonic potential system
The Schrodinger solutions for a three-dimensional central potential system whose Hamiltonian is composed of a time-dependent harmonic plus an inverse harmonic potential system are investigated. Because of the time-dependence of parameters, we cannot solve the Schrodinger equation relying only on the conventional method of separation of variables. To overcome this difficulty, special mathematical methods, which are the invariant operator method, the unitary transformation method, and the Nikiforov-Uvarov method, are used when we derive solutions of the Schrodinger equation for the system. In particular, and the Nikiforov-Uvarov method with an appropriate coordinate transformation enabled us to reduce the eigenvalue equation of the invariant operator, which is a second-order differential equation, to a hypergeometric-type equation that is convenient to treat. Through this procedure, we derived exact Schrodinger solutions (wave functions) of the system. It is confirmed that the wave functions are represented in terms of time-dependent radial functions, spherical harmonics, and general time-varying global phases. Such wave functions are useful for studying various quantum properties of the system. As an example, the uncertaintly relations for for position and momentum are derived by taking advantage of the wave functions.
