Spectroscopy of Confined Atomic Systems: Effect of Plasma

Ground-State Entanglement Properties of Helium Atom in a Finite Spherical Cavity

“…Here the non-linear parameter μ is iteratively determined so as to minimize the approximate energy (∂ E N /∂μ = 0). We concluded from our calculations that a rate of convergence of the method only slightly depends on parameter values in (2). For the sake of demonstration, the ground state energies obtained as described above are shown in Table 1 for A = 5 and for some different values of B as a function of N .…”

“…with eigenvalues (occupancies) λ nl related to the k nl coefficients in (4) by λ nl = ( 4π k nl 2l+1 ) 2 , where due to the 2l + 1 fold degeneracy, the normalization condition gives nl (2l + 1)λ nl = 1.…”

“…With the technological advancement, it is now possible to prepare control experiments with such systems in the laboratory. A detail discussion on these applications can be found in [1,2]. In particular, the research activity has expanded towards investigating properties of confined real two electron systems.…”

Precise energy eigenvalues of hydrogen-like ion moving in quantum plasmas

“…al. [15], on the behavioral changes in the structural properties of few-body systems embedded in external plasma environment, useful for laboratory and astrophysical plasma diagnostics determination. The most important part of such studies is to model the environment by an effective potential so that one can suppose as if the foreign atom/ion or the test charge will feel that effective potential while placed in or moving through that medium.…”

Natural and Unnatural Parity Resonance States in the Positron-Hydrogen System with Screened Coulomb Interactions

“…In a related development, atomic processes in plasmas have also attracted considerable attention (Ref. [27][28][29][30][31][32][33][34][35][36]). For weakly coupled plasmas such as Debye plasmas, the electronic interactions between charges are modeled with a screened Coulomb potential (SCP).…”
