Atomic Confinement

Study of a confined hydrogen‐like atom by the asymptotic iteration method

“…There are many reasons for this. The recent developments in nanotechnology have generated intensive research activity in modeling spatially confined quantum systems 1, 2. When an atom or a molecule is trapped inside any kind of microscopic cavity or is placed in a high‐pressure environment, it experiences spatial confinement that affects its physical and chemical properties 3, 4.…”

“…They suggested to replace the interaction of the atoms with surrounding atoms by a uniform pressure on a sphere within which the atom is considered to be en closed. This led them to consider the problem of hydrogen with modified external boundary conditions 2. Since then, the confined hydrogen atom attracted widespread attention 2–33.…”

“…This led them to consider the problem of hydrogen with modified external boundary conditions 2. Since then, the confined hydrogen atom attracted widespread attention 2–33. The approach to this confined problem is the same as that used to study a hydrogenic donor located at the center of a spherical GaAs ‐ ( Ga , Al ) As quantum dot, a semiconductor device that confines electrons 13–17.…”

Calculation of ground- and excited-state energies of confined helium atom

“…Recently considerable attention has been focused on the study of spatially confined atoms and molecules [1,2,3]. The confined atomic and molecular systems show substantially different ground state and response properties as compared to their free counterparts.…”

“…The study of confined atoms also provides insight into various properties of the quantum nanostructures like quantum dots or artificial atoms [11,12]. The detail discussion on these applications are available in several review articles [1,2,3].…”
