On the energy levels of a model of the compressed hydrogen atom

Density dynamics in some quantum systems

“…[202][203][204][205][206][207] There have been wide applications of confined quantum systems such as in physics, chemistry, and biology. [201,[208][209][210][211][212] The models of confined quantum systems such as confined atoms and confined molecules have been used to study matters under high pressure. The confined systems and their free counterpart behave differently owing to the fact that confinement brings about modifications of certain properties.…”

“…The confined systems and their free counterpart behave differently owing to the fact that confinement brings about modifications of certain properties. [201,[208][209][210][211][212][213][214][215] . A detailed study about the effect of confinement, both spherical [213][214][215] as well as cylindrical, [216] on the chemical reactivity of atoms have been pursued.…”

Photoionization Cross Sections of Atomic Impurities in Spherical Quantum Dots

“…The confined atomic models are widely used to study a variety of physical systems, such as impurities in quantum dots (Lin & Ho (2011)), atoms encapsulated in fullerenes (Connerade et al (1999); Dolmatov et al (2004)), and atoms under high pressure (de Groot & ten Seldam (1946); Michels et al (1937)). In this article, we focus on the quantum confinement occurring in quantum dots.…”

Electron density and its derivatives at the nucleus for spherically confined hydrogen atom

“…The spherically confined hydrogen atom [1], (SCHA), has been extensively studied [2][3][4][5][6][7][8][9][10][11] as a standard model for confined electronic atoms. A majority of such studies have focussed on the confining effects because of an impenetrable central potential located at the radius of confinement R. Relatively fewer studies have been reported [9][10][11] which include the finite (penetrable) wall.…”
