Theory Advances in High-Precision Two-Photon Spectroscopy
… Dynamic polarizabilities of relevant S and D states, quantifying the dynamic Stark shift, and transition matrix elements among these states are calculated, taking into account leading-order relativistic, radiative and non-dipole laser-field effects. An important broadening effect of the …

Electron-beam-pumped recombination lasers
… the production of the 7$\sp3$S and 6$\sp3$D states of Hg, of which 7$\sp3$S is the upper level of the reported laser. For the neon laser, the dominant recombining ion has been previously shown to be Ne$\sb2\sp{+}.$ One of the dominant roles of helium in recombination lasers is inferred from …

Ultrafast Dynamics and Nonlinear Interactions in Alkali Atoms and Diatomics
… the rovibrational dynamics of the B, C, and D states of the Cesium dimer and to study atomic wavepackets and nonlinear effects in Rubidium and Potassium. Two color, pump-probe techniques have been used to probe the time evolution of wavepackets in the B, C, and D rovibrational levels of …

Ab-initio calculations for dilute magnetic semiconductors
… simpler problem of understanding the density of states, in particular those features in the spin dependent local density of states resulting from the hybridization with the orbitals of neighboring impurities. Based on this analysis we found and investigated four different exchange mechanisms …

Probing weakly bound long-range Rydberg molecules by quantum beating experiments in rubidium vapor
… molecules (LRRM) associated with rubidium atomic states with low angular momentum and very low principal quantum numbers (7$s$, 8$s$, 5$d$, 6$d$) are observed in a quantum beating experiment for the first time. The experiments are conducted using parametric four-wave mixing (PFWM) in a pump-probe …

Topics in the theory of semiconductors
… to the valence-band maxima are due to the d-states. In part II, the electronic structures of the pseudobinary alloy semiconductors Pb1_xSnxTe are analyzed using the tight-binding model with spin-orbit interaction. The density of states and the band gap at the L point are computed for both the …

Molecular Electronic Structure via Photoelectron Imaging Spectroscopy
… Ground and excited C₄H₃S and C₄H₃O radical states are observed, and bond dissociation energies are defined. Next, a new model used to qualitatively analyze photoelectron angular distributions resulting from mixed s - p hybrid states is presented and applied to detachment from pyridinide, …

Photoconductivity in amorphous silicon
… as due to recombination in distributed states, which are restricted in energy, extending from the dark Fermi level upwards to 0.6eV below E<sub>c</sub>. The capture cross section of these states was of a value expected for the neutral dangling bond, so they have been denoted as D states. …

Steady state and transient photoconductivity in n-type amorphous silicon
… multiple trapping and saturation of the trap states above the electron quasi-Fermi level,<br/>which allows determination of the distribution of conduction band tail (CBT) states, and hence comparison of the quality of the two materials. A broad exponential tail of high state density was found …

Body, Mind, Spirit: In Pursuit of an Integral Philosophy of Music Teaching and Learning
… development; c) lines of human development; d) states of consciousness; and e) types or styles of being and acting in the world. Finally, this dissertation applies Integral Theory's multi-perspective approach to the dynamic elements that engage body, mind, and spirit as teacher and learner …

Theory of magnetic transition metal nanoclusters on surfaces
… with a rather weak hybridization of the Ni d-states with the adatom d-states to the case of Fe(3ML)/Cu(001) with a much stronger hybridization due to the larger extend of the Fe wavefunctions. Cr and Mn clusters of different sizes and shapes have been found to exhibit non-collinear magnetic …

Enhancing the mechanical and chemical integrity of Ag/ZnO-based transparent and conductive thin film coatings: an atomistic modelling study
… the hybridisation of Ag-dopant electronic states and is enhanced if the dopant contains desired d-states. By carefully choosing the dopant type the Ag/ZnO interfacial adhesion can be improved. A new strategy is proposed to limit Ag interdiffusion in ZnO by elemental doping. First principles …

All-electron GW calculations for perovskite transition metal oxides
… it is particularly suitable to describe d and f states of transition metals and rare earths contained in the perovskite TMOs. Trends in the electronic structure of three series of prototypical perovskite TMOs including BaTiO3, BaZrO3, and PbTiO3 in the high-temperature cubic crystal phase are …
