We calculate energies of shallow donors confined in a rolled-up quantum well the presence electric field by solving numerically Schrödinger equation natural curvilinear coordinates. It is found that curves density states (DOSs) are very sensitive to variation donor position, geometry spiral and applied value. Novel results for dependencies donor’s dipole moment its polarizability on strength or...

Semiclassical behavior of Stark resonances is studied. The complex distortion outside a cone introduced to study in any energy region for the Hamiltonians with non-globally analytic potentials. non-trapping resolvent estimate proved by escape function method. Weyl law and resonance expansion propagator are shape model. To prove theorem, functional pseudodifferential calculus effect established,...

We present a detailed comparison between the first order Stark-effect induced Gailitis resonance in e+ + H (n = 2) and the second order Stark-effect induced resonance in e + Ps (n = 1). Common characteristics as well as differences of these resonances will be identified. These results will be used to assess the presence of Gailitis resonances in the scattering of proton on the ground state of 7...

We report on an experimental and theoretical study of the dynamic (ac) Stark effect on a forbidden transition. A general framework for parameterizing and describing off-resonant ac-Stark shifts is presented. A model is developed to calculate spectral line shapes resulting from resonant excitation of atoms in an intense standing light-wave in the presence of off-resonant ac-Stark shifts. The mod...

T he Stark III regulations that went into effect on Dec. 4 include a number of developments that might significantly help family physicians. Part one of this two-part series of articles addressed significant changes for physicians in group practices. (See “Stark III: Refinement Not Revolution (Part 1),” FPM, March 2008.) This article addresses issues tied to the relationships between physicia...
