Abstract:Exact solutions of a pseudoharmonic oscillator and a family of isospectral potentials are investigated in spherical coordinates. The entropic moment, generalized quantum similarity index, and some quantum information measures are investigated analytically and numerically for two density functions of two quantum systems with same energy and one quantum system with different energies. Analytical results are compared for 19 selected molecules and verified by some physical and artificial values of the spectroscopi… Show more

“…Recently complexity ratio has been introduced in position and momentum spaces for radial pseudoharmonic oscillator potential [47]. With respect to generalized quantum similarity index [48], we already shown that, wave functions of some diatomic molecules are same for pseudoharmonic oscillator, which are matched with a family isospectral potentials in 3D [49].…”
Rényi complexity ratio of two density functions is introduced for three and multidimensional quantum systems. Localization property of several density functions are defined and five theorems about near continuous property of Rényi complexity ratio are proved by Lebesgue measure. Some properties of Rényi complexity ratio are demonstrated and investigated for different quantum systems. Exact analytical forms of Rényi entropy, Rényi complexity ratio, statistical complexities based on Rényi entropy for integral order have been presented for solutions of pseudoharmonic and a family of isospectral potentials. Some properties of Rényi complexity ratio are verified for six diatomic molecules (CO, NO, N2, CH, H2, and ScH) and for other quantum systems.

“…If wave functions of any one Hamiltonian H − (or H + ) are known, then one can obtain another set of wave functions for the Hamiltonian H + (or H − ), using super-symmetric quantum mechanics and they are obtained from [45,54,55,56,57]…”

Exact solutions of time-dependent Schrödinger equation in presence of time-dependent potential is defined by point transformation and separation of variables. Energy and Heisenberg uncertainty relation are pursued for timeindependent potential whereas average energy and Heisenberg uncertainty relation are defined for time-dependent potential. Forces acting on a fixed boundary wall as well as average force acting on moving boundary wall are presented along various trajectories. For high temperature, analytical forms of partition function and the corresponding thermodynamic quantities are derived following the Euler-Maclaurin summation formula over a finite as well as an infinite domain for accurate presentation. Three quantum systems are generated with the help of point transformation, separation of variables and super-symmetric quantum mechanics from one quantum system and the corresponding results are compared among all systems, where two of them are time-independent and another two are time-dependent.

Next, we will investigate the connection between the majorization and the localization property of continuous density functions.…”
The majorization effect on some entropic functionals, such as von-Neumann, Shannon, atomic Wehrl and Rényi entropies are investigated of a vee type three-level atom which interacts with a coherent field in a resonant cavity.Moreover, the fidelity, purity and linear entropy are investigated of two quantum systems, which contain photon number distributions (discrete) and Husimi Q function (continuous distribution). A relation between the majorization and localization properties of continuous density functionals is established. The results are compared and verified for continuous and discrete distributions.
