The ground state and excited states energies of 2-electron quantum dot with spherical harmonic oscillator type potential has been determined. The energy spectrum and wave functions for the quantum dot of asymmetric confinement are obtained by analytically solving the eigenvalue equation in the magnetic field. The effect of various relativistic corrections to kinetic energy, Darwin term and spin-orbit for the zero-dimensional structure to the energy eigenvalues and wave functions is also investigated. The thermal properties like internal energy, entropy and free energy are discussed graphically with radius of quantum dot and pressure and are found to have interesting dependence on the radius and pressure parameter with relativistic corrections for our model.

To scrutinize the role the weak interactions in structure-stability of [ZnX] - (X = Cl, Br, I) based derivatives, three series of inorganic-organic hybrid materials were studied through single crystal X-ray crystallographic data obtained from IUCr in CIF format. The organic constituent of the hybrid compounds is holding the inorganic moiety through D-H…X interactions, where D is N, C or O of organic moiety acts as H-donor atom and X of inorganic component is Cl, Br I or F behaves as H-acceptor atom. The structural parameters such as the Zn-X bond distance lies in the range of 2.019(5) A [ZnF-3] to 2.730(4) A [ZnCl-1] and X-Zn-X bond angle has minimum value of 82.35 o and maximum value of 180 o for [ZnF-3], were calculated. The maximum twist of X-Zn…Zn-X = 179.8(3) o at symmetry position of 0.5+x, 0.5-y, 0.5+z is observed in [ZnBr-7] derivative.

An extensive set of energy levels, inverse radiative rates, wave-function composition in LSJ and JJ coupling schemes for the lowest 162 fine structure levels along with transition wavelengths, oscillator strengths, line strengths and transition probabilities for electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2) and magnetic quadrupole (M2) EUV and SXR transitions from the ground state have been presented for Ba XLVI. For these calculations, the fully relativistic Multiconfiguration Dirac-Fock (MCDF) approach is employed. The QED corrections due to vacuum polarization and self-energy effects and Breit correction due to the exchange of virtual photons between two electrons are fully considered. To assess the authenticity and credibility of presented results, analogous calculations have also been performed by using a fully relativistic configuration interaction program (Flexible Atomic Code) based on self-consistent Dirac-Fock-Slater iteration method. Extreme Ultraviolet (EUV) and Soft X-ray (SXR) transitions are also identified. Comparison is also made with the available experimental and theoretical data. These accurate data are expected to be useful in fusion research and astrophysical investigations and applications.

Substitutional study of Zn on YBa(_2)Cu(_{3-x})Zn(_x)O(_{7-delta}) ((0 < x < 0.1)) have been carried out on polycrystalline samples to determine the effect of Zn doping in small concentration on the instability of the unit cell structure in the presence of water. YBa(_{2-x})Sr(_x)Cu(_{3})O(_{7-delta}) and YBa(_2)Cu(_{3-x})Al(_x)O(_{7-delta}) polycrystalline samples for various concentration of Sr((0 < x < 0.6)) and Al((0 < x < 0.6)) have also been treated with water. The degree of degradation in the substituted samples is a function of the type of the dopant Sr(^{2+})/Al(^{3+})/Zn(^{2+}) as well as the molar concentration of the dopant. The degradation is found to be minimum in the case of Sr(^{2+}) substitution at Ba(^{2+}) sites in YBa(_2)Cu(_3)O(_{7-delta}) as compared to the degradation of Al(^{3+}) and Zn(^{2+}) substitution at Cu((1)) and Cu((2)) sites, respectively. The degradation is maximum in the case of Zn(^{2+}) substitution at Cu((2)) site. The studies were made using R-T measurements, X-ray diffraction technique and iodometric titration method and SEM.

We study the spin current in a quantum wire subjected to magnetic fields in the presence of Rashba spin orbit interaction. For an infinite superlattice wire, we find that the spin current density is strongly affected by the nature of the sub bands. The results are presented as a function of transverse coordinate, magnetic field and Rashba spin orbit interaction strength. Our results indicate an increase of spin current density with the increase of Rashba factor. The roles of confinement strength and magnetic fields as control parameters on the spin current have been demonstrated.

We consider high harmonic generation from a quantum dot (QD) in the presence of chirped laser pulse. The system dynamics is described by coupled equations which are solved numerically for various material parameters of QD and external laser field. Results show the effective controlling effect on the generation of High Harmonic Generation by changing the Chirping parameter of the laser pulse and the size of the QD which otherwise is not possible in other systems.

Electron impact excitation of Fe-like tungsten ion has been studied using relativistic distorted wave theory. Cross-sections are obtained in the energy range upto 20 keV and their fitting is also provided for their potential application in plasma modeling. Polarization of the photon emission following the decay of the excited states is also analysed.

A density matrix based complete analytical solution for the probe transmission through a three-level cascade type Doppler free atomic system is obtained. The probe beam couples the ground level to the energy level lying at the middle whereas the control field is acting between the level at the middle and the upper most energy level. The analysis is valid for comparable values of probe and control Rabi frequencies too. The probe response shows EIT window when Raman condition is satisfied. The variation of the EIT width with control Rabi frequency under Doppler free condition is studied using the parameters of (5S_{1/2}rightarrow 5P_{3/2}rightarrow 5D_{5/2}) transitions of (^{87})Rb. At high value of the probe field intensity compared to that of the control field, enhancement in probe absorption is noticed. The increase of the EIT width with control Rabi frequency under Doppler free situation is examined.

We have recently build a new experimental station with a beam line dedicated to atomic collision physics at the 5 MV TANDEM accelerator of the Institute of Nuclear and Particle Physics at the National Research Center “Demokritos” in Athens, Greece. A complete zero-degree Auger projectile spectroscopy apparatus composed of a single stage hemispherical spectrograph and a 2-dimensional position sensitive detector combined with a doubly differentially pumped gas target has been set up for high resolution studies of electrons emitted from projectile ions excited in collisions with target atoms. With the new setup we have started a systematic isoelectronic investigation of K-Auger spectra emitted from pre-excited ions in collisions with gas targets using novel techniques. Here, we present some of our first new results involving collisions of carbon He-like ions with target gases. These results are expected to lead to a deeper understanding of the neglected importance of cascade feeding of metastable states in collisions of ions with gas targets and further elucidate their role in the non-statistical production of excited three-electron states by electron capture, recently a field of conflicting interpretations awaiting further resolution.

A comparative study of target ionization processes of Hydrogenic ions by Positronium impact are investigated. Calculations are performed using the Coulomb distorted eikonal approximation. Interesting qualitative features are noted both in the scattered Ps and the ejected electron distributions in triple differential as well as double differential cross sections. The Ps impact ionization of three hydrogenic ions shows some distinct variation from the electron impact ionization.
