“…This limited DH approximation has generated the redshift of the Lyman-α line of the H-like ion in a plasma environment in agreement both with the experimentally observed value and the data from more elaborate simulations based on quantum mechanical approaches [27]. Its applications to the α emission lines of both hydrogen and helium-like ions which meet the spatial and temporal criteria have also led to simple scaling properties of the redshifts of the transition energies as well as the oscillator strengths [20,27,28]. For more complex ions, it is expected that a full-relativistic application of the DH approximation is necessary to include the electron correlations as well as the relativistic effects.…”

“…The influence of the plasma environment to the atomic processes is a challenging many-body problem and several sophisticated and complicated models were developed over the years to understand such processes [21][22][23][24]. On the other hand, the Debye-Hückel (DH) model, with its simplicity [25], could easily capture the important qualitative features over several orders of magnitude in plasma temperature and density, and, at the same time, offer the physical interpretation as a reliable reference for other theoretical models [20,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Recently, we present a critical assessment of the DH approximation in terms of the spatial and temporal criteria for dense plasma which limits its applicability to atomic processes that are short-ranged in nature for the H-like and He-like ions with nucleus charge Z between 5 and 18 [20,27,28].…”

We present the results of a detailed theoretical study which meets the spatial and temporal criteria of the Debye-Huckel (DH) approximation on the variation of the transition energies as well as the oscillator strengths for the 2p 5 3d 1 P 1 → 2p 6 1 S 0 (3C line) and the 2p 5 3d 3 D 1 → 2p 6 1 S 0 (3D line) transitions of the Ne-like ions subject to external plasma. Our study shows that the redshifts of the transition energy follow the general scaling behaviors similar to the ones for the simple H-like and He-like ions. Whereas the oscillator strength for the 3C line decreases, the oscillator strength for the spin-flipped 3D line increases as the strength of the outside plasma increases. As a result, their ratio is amplified subject to outside plasma environment. We further demonstrate that the plasma-induced variation between the relative strength of the 3C and 3D transitions is mainly due to the spin-dependent interactions which dictate the mixing of the 1 P 1 component in the 3 D 1 upper state of the 3D transition. In addition, we are able to find that the ratio between the relative oscillator strengths of the 3C and 3D lines in the presence of the plasma to their respective plasma-free values varies as a nearly universal function of [(Z − 9.2)DZ] −1.8 , with Z the nuclear charge and D the Debye length. The results of this study should be of great help in the modelling and diagnostic of astrophysical plasmas as well as laboratory plasmas.

“…Several (both variational and perturbative) methodologies are available for the exact and approximate calculation of the effects of dense plasma environments on the atomic structure and collision process that could allow accurate plasma diagnostic studies. Based on the spatial and temporal criteria of the Debye-Hücke (DH) approximation, Fang et al [21] reported a theoretical study on the lineshifts of the 1s2p 1 P 1 ! 1s 2 1 S 0 line of He-like ions subject to outside dense plasmas.…”

The correct understanding of the behavior of highly stripped ions immersed in a dense plasma environment is a hitherto challenge for theory and it is of importance in various applications. Here, we developed four kinds of novel theoretical models to the determination of the spectral properties and collision dynamics of H-like ions in dense and hot plasmas by employing the analytical potential [Li et al., Phys. Plasmas 2019, 26, 033301] to describe the interactions among the charged particles: (i) The electron photon processes in plasma model within the relativistic scheme; (ii) The multiconfiguration Dirac-Fock model within the framework of relativistic self-consistent iteration approximation; (iii) The generalized pseudospectral method within the relativistic framework; and (iv) An analytic formula based on the Hartree-Fock method and the irreducible tensor theory within the non-relativistic regime, derived from a solution of Schrödinger equation. As a typical example, energy eigenvalues, radiative transition properties, spectral line shifts, and electron impact excitation and ionization cross sections of the selected N 6+ and Ne 9+ ions are determined for several temperature-density cases, characteristic of inertial confinement fusion plasmas. A comparison of these results with each other and the results from earlier calculations as well as with the available experimental data is provided. Systematic trend is determined for all the Zhan-Bin Chen and Peng-Fei Liu contributed equally to this study.

“…Here we just show how the transport behavior is modified by varying photon-emitter interaction strength and by tuning the emitter transition frequency. It should be pointed out that a pair of detuned two-level system separated by a half wavelength may behave like a driven Λ-type three-level system, and the electromagnetically induced transparency is expected to occur at certain detunings [33].…”

Single-photon transport in an array of quantum emitters with long-range interactions

We investigate photon transport in a waveguide coupled to two-level quantum emitters with longrange interactions. We derive an exact solution for transmission and reflection amplitudes in the framwork of real-space Hamiltonian. Our explicit formula allows for a complete description of photon transport in the presence of N quantum emitters with arbitrary non-local interactions. We apply this approach to single-photon transport in an one-dimensional waveguide coupled to two atoms with dipole-dipole interaction (DDI). Our numerical results confirm the Fano spectrum line shapes as a result of strong DDI, and demonstrate how the split of perfect reflection spectrum and the resonance transmission can be achieved by tuning the photon-atom and the atom-atom interactions.
